add a parameter to makeTokenParser to specify options for treating space by lexeme

Sometimes space around tokens matters a lot. Take Haskell dot for example.

This proposal is to add a parameter to `makeTokenParser`

https://github.com/haskell/parsec/blob/38dfc545874dd44c26382d8dd692eb533396c6f5/src/Text/Parsec/Token.hs#L358-L361

which would explicitly specify lexeme options:
- consume trailing space
- do not consume trailing space
