This implements the `bitwise` namespace for expressions that allows performing bitwise operations on booleans, integers and floating point values. This also allows for bitwise aggregations. List of implemented functions: - [x] `bitwise.count_ones` - [x] `bitwise.count_zeros` - [x] `bitwise.leading_ones` - [x] `bitwise.leading_zeros` - [x] `bitwise.trailing_ones` - [x] `bitwise.trailing_zeros` - [ ] `bitwise.and` - [ ] `bitwise.or` - [ ] `bitwise.xor` [skip ci]

There was a problem hiding this comment.
We can add these to Series as well. If you create the functions without implementing them, they will automagically dispatch to these expresssions (via a decorator).
And then the docs entries. :)
