Type hints in column names

[calpaterson]

Brief overview

AS A user trying to paste a troublesome csv file

I WANT to add an explicit type hint to the column name

SO THAT I can bypass sniffing of the column type

Additional details

Probably something like My column name::integer. Python uses colons but SQL/ML-type langs use double colon, which is less likely to be an accident.

My column::nonsense should be ignored
