Added

- Added `Pipeline`'s to move all piping to them

Added

- Result helpers: `if_ok`, `if_err`, `is_ok`, `is_err`.
- Option helpers: `if_some`, `if_none`, `is_some`, `is_none`.
- Sequence helpers: `imap`, `ifilter`, `ireduce`.
- Pipeline helper: `funml.execute()`.

Changed

- Changed creation of records to use classes decorated with `record`
- Changed creation of enums to use classes subclassed from `funml.Enum`
- Removed `map` and `filter` methods of `IList`

Fixed
