Description

https://github.com/apache/avro/blob/b8937526d32928b3b29040e862f7689d7230bddb/lang/rust/avro/src/types.rs#L405

Currently a Avro value of the type float (32) cannot be resolved against a schema where the type is defined as double (64). We already support type widening from int -> long (dest. schema) as this is completely lossless, so I think we should also support the same for float -> double for consistency & convenience as this is a common use case.
