Remove reexport of bits::* in crate root (#1485)

* Remove reexport of bits::* in crate root

This reexport seems to be a remnant from the days of macro parsers,
which no longer exist.

It has caused confusion on several occasions. nom::complete::tag, for
example, refers to nom::bits::complete::tag, while users actually want
nom::bytes::complete::tag in the vast majority of cases.

+- `nom::bits::*` is no longer re-exported at the crate root. This export caused frequent confusion, since e.g. `nom::complete::tag` referred to `nom::bits::complete::tag` instead of the much more commonly used `nom::bytes::complete::tag`. To migrate, change any imports of `nom::{complete::*, streaming::*, bits, bytes}` to `nom::bits::[...]`.
