feat: Bitwise operations / aggregations

[coastalwhite]

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:

• bitwise_count_ones
• bitwise_count_zeros
• bitwise_leading_ones
• bitwise_leading_zeros
• bitwise_trailing_ones
• bitwise_trailing_zeros
• bitwise_and
• bitwise_or
• bitwise_xor

I think we can skip that test on py39. :')
