Currently the `FieldRef` string representation looks like
`"FieldRef.Name(col)"` or `"FieldRef.Nested(FieldRef.Name(col)
FieldRef.Name(field1))"`.
While being explicit and descriptive, those representations also show up in
error messages (also on the Python side), eg when a certain field reference is
not found in the schema, or show up in the repr of expressions.
I don't what would be the best tradeoff between still descriptive and clear
but also concise and nice to read, but I think I would prefer something like
`FieldRef("col")` or `FieldRef(("col", "field1"))` (I don't know if it is a
problem that the repr would include quotes, and this also doesn't yet include
field paths).
Or even an option to just get the name `"col"`, such that you can combine
that more in a sentence like "No match for field ref <name>".
