Release 0.3.0 (#47)

## Description

### Added

- Additional testpath flag in conftest
- Symbolic parsing mode for ``build_unit_cell``

### Changed

- ``build_unit_cell`` has a symbolic computation mode that allows for
more accurate
  construction of unit cells.

### Fixed

- Accessing data pairs with ``get_from_pairs`` or ``__getitem__`` now
allows for case-insensitive searches
- Quote-delimited strings containing the delimiting character are now
parsed properly
- ``build_unit_cell`` now rounds coordinates before wrapping into the
box, fixing edge cases
  where boundary atoms were not properly deduplicated
