Describes how a row can be decoded to the given type.
RowDecoderF provides convenient methods such as map, emap, or flatMap
to build new decoders out of more basic one.
Actually, RowDecoderF has a cats `MonadError`
instance. To get the full power of it, import cats.implicits._.

Similar to or, but return the result as an Either signaling which row decoder succeeded. Allows for parsing an unrelated type in case of failure.

- Type parameters:
- B
the type the alternative decoder returns
- Value parameters:
- cd
the alternative decoder
- Returns:
a decoder combining both decoders
Map the parsed value, potentially failing.
Map the parsed value, potentially failing.
- Type parameters:
- T2
the result type
- Value parameters:
- f
the mapping function
- Returns:
a row decoder reading the mapped type
Map the parsed value to a new decoder, which in turn will be applied to the parsed value.
