v0.3.0

Added

Added methods for obtaining Chess960 start positions from their Scharnagl number.
Added PEXT bitboards using the BMI2 PEXT intrinsic. Potentially faster than the default algorithm. Enable using the pext feature.
Added Board::hash_without_ep method for fast equivalence checks excluding the en passant square.
Added Board::same_position to check if two boards are equivalent under FIDE rules.
Added Board::colored_pieces, a shorthand for board.colors(color) & board.pieces(piece).
Added BitBoard::is_subset, BitBoard::is_superset, and BitBoard::is_disjoint.

Changed (breaking)

BitBoards now operate in a more set-wise manner instead of acting like a u64. Bit operators changed to match set operators.
BitBoard::popcnt renamed to BitBoard::len for consistency with other data structures.
BoardBuilder's fullmove_number field changed to a u16 for usability reasons.
Board's FromStr implementation now parses both FEN and Shredder FEN.

Removed (breaking)

BitBoard no longer implements Iterator directly.
Sliding move functions are no longer const by default; Use the const variants if required.
Unnecessary "try" variants on Board removed; The risk of panicking is accepted when *_unchecked methods are called.

Fixed

Overflow bug in Square::try_offset fixed.
FenParseError is no longer unnameable.
Fixed incorrect errors being returned in FEN parsing.
Fixed some errors not being produced in FEN parsing.
