* adding a new parameter to the `get_utxo_by_address` query to allow for multiple addresses to be passed in.
* adding a new tag to support address encoding using [minicbor](https://github.com/agilulf/minicbor).
* moving the `address` type from `pallas-addresses` to `pallas`.
* updating imports and usages of `miniprotocols` to use the `pallas` namespace.

the changes made to `codec.rs` include:
- replacing `metadatum` with `value` in the `decode` and `encode` implementations for `request`
- replacing `metadatum` with `value` in the `decode` and `encode` implementations for `metadatum`
- replacing `metadatum` with `value` in the definition of `multiasset` in the `mod.rs` file

updates the codec and mod modules in the `pallas-network` project to fix a bug. it removes the `int` type from the `pallas_codec::utils` module in the `mod.rs` file, and removes the `tag` type from the `pallas_codec::minicbor` module in the `codec.rs` file.

the changes include:
- updating `use pallas_codec::utils` to include `bytes`, `tagwrap`, and `anycbor`
- adding a `hex_datum` string with a corresponding `datum` byte array and a `tag`
- adding an `inline_datum` field to the `localstate::queries_v16::values` values
- adding the `inline_datum` to the `keyvaluepairs` array for the `utxo` query
- updating the `keyvaluepairs` array for the `utxo` query response
- updating the `keyvaluepairs` array for the `contract` query
- updating the `keyvaluepairs` array for the `contract` query response
