* Added a CHANGELOG.md file
* Adapted config.md example of vault usage
* Adapted some of the command descriptions to be more consistent

* Added support to show g1v1 base58 public key from (ed25519) ss58 address, AccountId, ed25519::Public with tests for those
* Renamed SecretFormat.Cesium to SecretFormat.G1v1
   * Adapted `clap` display help to reflect the change
   * Still supporting using "cesium" as "-S" secret format argument and mapping it to SecretFormat.G1v1
* Adapted display of vault
   * Changed column "Format" into "Crypto", showing either "ed25519" or "sr25519" instead of "cesium" or "substrate"
   * Adapted 1st row header to "SS58 Address/G1v1 public key"
   * For "ed25519" account, showing a 2nd row just below containing "└ G1v1: <base58 public key value>"
   * Adapted test cases and added a G1v1 account example
* Adapted (String) Display of vault_account to include "g1v1_pub_key" value when crypto_scheme is Ed25519

* Started to investigate being able to make subkey command and trying to use sp_core::crypto::CryptoType instead of custom KeyPair
* Big refactoring to have all in one vault_account db table; using recursion through `parent` property
* Added AccountTreeNode object and related methods to be able to more easily handle whole tree of accounts
* Removed now unused vault_derivation
* Replaced remaining usages of `rpassword` and removed the dependency
* Added `indoc` dependency to support cleaner display of multi-line strings in tests

* Cleaned-up code in several places
* Now retrieving secret value in "substrate uri" format from the different prompt_xxx_and_compute_keypair methods

* Added a test to verify we don't need the nacl::sign::Keypair to handle cesium v1 (we can keep using scrypt to retrieve the seed and then sp_core::ed25519::Pair)
** This means we could remove some code linked to that and possibly the `nacl` dependency.

* Added "/.idea" exclusion in .gitignore (for when using JetBrains IDEs)
* Added dialoguer dependency for easier user input handling (see in inputs.rs)
* Added sea-orm dependency to allow having DB entity mappings and use a local sqlite file database
* Added rstest test dependency for parameterized tests support
* Added derivation tests for each SecretFormat (including cesium v1 key derivation, using sp_core::ed25519::Pair)
* Made a lot of changes to add vault_account and vault_derivation db tables to persist vault keys & derivations
* Added support for KeyPair::Ed25519 linking to sp_core::ed25519::Pair which can be created from secret seed retrieved from nacl::sign::Keypair (which is created from cesium id + secret)
** This was necessary to allow deriving keys from "cesium v1" keys (to be reviewed - it might be a bad idea to permit that from a security point of view)
* Only kept original (substrate) keyfiles support for migration (use "vault list-files" and "vault migrate")
* Added possibility to give either "-a" Address or "-v" Vault Name as general option
* Added extra commands in Vault
** list-files: (deprecated)List available key files (needs to be migrated with command "vault migrate" in order to use them)
** migrate: (deprecated)Migrate old key files into db (will have to provide password for each key)
** 'list' now has sub-commands 'all' or 'root' to show all keys or only root keys (without derivation path)
** use: "Use specific vault key (changes the config address)", which will have the same behaviour as `gcli <-a <Address>|-v <VaultName>> config save` (left a FIXME in there to review)
** derivation: Add a derivation to an existing (root) vault key
** rename: Give a meaningful vault name to a vault key or derivation
** remove: Remove a vault key (and potential derivations if it's a root key)
* Had to bubble up "await" and "async" in a lot of places
* ...
