Added
Added `solders.message.to_bytes_versioned` and `from_bytes_versioned` to serialize versioned messages including the extra leading byte [(45)](https://github.com/kevinheavey/solders/pull/45)
Fixed
`transaction.Legacy` no longer implicitly casts to int when checking equality. This was breaking tx version checking when tx version was returned as `Legacy | int` [(44)](https://github.com/kevinheavey/solders/pull/44)
