Xrpl-py

Added:
- Support for dynamic fee calculation
- Function to parse account balances from a transaction's metadata
- Better error handling for invalid client URL
- Exported SubscribeBook

Fixed
- Resolve `txnNotFound` error with `send_reliable_submission` when waiting for a submitted malformed transaction
- Small typing mistake in GenericRequest
- Fix bug in GenericRequest.to_dict()

Added
- Support setting flags with booleans. For each transaction type supporting flags there is a `FlagInterface` to set the flags with booleans.
- `federator_info` RPC support
- Helper method for creating a cross-chain payment to/from a sidechain
- Helper method for parsing an NFTokenID

Fixed
- Updated NFT names to match new 1.9.0 rippled names
- `xrpl.asyncio.clients` exports (now includes `request_to_websocket`, `websocket_to_response`)
- Adds optional `owner` field to NFTokenBurn
- Allows lower-case currency codes

Added
- Sync and async `generate_faucet_wallet` functions now support a custom
faucet host

Added
- Support for the [XLS-20 NFT proposal](https://github.com/XRPLF/XRPL-Standards/discussions/46)
- `xrpl.models.amounts.get_amount_value` helper function
- `xrpl.utils.str_to_hex` and `xrpl.utils.hex_to_str` helpers
- `ledger_index` optional param for all the main account methods
- `TicketCreate` transaction model
- `GenericRequest` model for unsupported request types
- Methods to convert between `IssuedCurrency` and `IssuedCurrencyAmount`
- Support for ints and floats in the `IssuedCurrency` and `IssuedCurrencyAmount` models (and ints for `XRP`)
- `max_fee` and `fee_type` optional params for `get_fee`
- `autofill`, a new public method that populates the `fee`, `sequence`, and `last_ledger_sequence` fields of a transaction, based on the current state retrieved from the server the Client is connected to. It also converts all X-Addresses to classic addresses.
- Exports `Transaction`, `Response`, pseudo-transactions at the `xrpl.models` level

Fixed
- Improves typing of `Response.result`
- Makes the default ledger version for `get_next_valid_seq_number` `current` instead of `validated`
- Stops erroring on non-`tesSUCCESS` responses in reliable transaction submission
- Removes runtime asserts in websocket clients that were used for type checks only
- Adds missing top-level `py.typed` file for exceptions and constants
- Fix issue where unsupported currency codes weren't being correctly processed in the binary codec
- Fixes issue with UNLModify encoding (due to a bug in rippled)
- Makes the account delete fee dynamic, based on the ledger's reserve, instead of hard-coded
- Fee scaling based on load on the ledger
- Fixes potential issue with conflicting Decimal contexts
- Fixes bug where autofilling using an `xAddress` with `None` in the Destination Tag threw a KeyError

Added
- Support for Python 3.10

Fixed
- Improves documentation on using websocket clients.
- Fixes an issue sending NoRippleCheck requests
- Allows projects that use xrpl-py as a dependency to use typing

Fixed
- Fixes an issue encoding some non-standard currency values
- Corrects installation instructions in documentation
