Added
- `encoding` argument to `Ontology` constructor to skip auto-detection if needed ([221](https://github.com/althonos/pronto/issues/221), [#241](https://github.com/althonos/pronto/issues/241)).
Fixed
- Broken implementation of `EncodedFile.readinto` causing issues with some encodings ([109](https://github.com/althonos/pronto/issues/109)).
- `tests` module being included in site-install ([237](https://github.com/althonos/pronto/issues/237)).
- Ignore Unicode BOM in `BaseParser.can_parse` if any.
