feat: missing filter builder functions

also implement a custom and simpler DSL
to represent conditions to be used in
`any_of`, `all_of` functions

renamed:
- `and/2` to `all_of/2`
- `or/2` to `any_of/2`
- `in/2` to `within/2`
- `not/3` to `negate/3`

to avoid conflict with [Kernel](https://hexdocs.pm/elixir/Kernel.html)
