Add `deserialize` to `BatchSerializer`

[jayzhan-synnada]

Which issue does this PR close?

• Closes #.

Rationale for this change

we have serialize already, and it would be nice to have another deserialize so we can convert the output of serialize back to RecordBatch

Also, both method are changed to async, since most of the time we prefer async function for serialization in case it takes a long time

What changes are included in this PR?

Are these changes tested?

Are there any user-facing changes?

[berkaysynnada]

I've two questions: 1) Why don't we use BatchDeserializer to deserialize? 2) Why are we converting them to async as they don't yield at all already?

[jayzhan-synnada]

BatchDeserializer can do what I want so we don't need this.

Maybe we can fix the code structure, it would be nice that they are close together and clear that we can deserialize and serialize with these 2.
