Patch datum factory for specific data in IOs

[RustedBones]

Quick patch for apache/beam#28279

Unfortunately, contains some code duplication:

• avro coder still in scio-core
• SMB avro not in scio package + not streamlined with beam AvroIO

[RustedBones]

SMB avro read was not symmetric with writer and did not have any logical type conversion applied.

[shnapz]

We were lucky nobody used logical types in SMB?

[RustedBones]

Looks like it yes
