v0.6.0.0

• Updated some dependencies. Now Nekomata can be built with GHC 9.8.1.
• Fixed a bug in printing truncated results.
• Now characters are internally represented as Word8s instead of Chars.
• Added a REPL command \Arity to print the arity of a function.
• New built-in functions: elem, \filterBy, \minValue, \minMax, \maxValue, \ordering, \pad, \slices.

Breaking changes

• \apply2 is renamed to \onBoth.
• \interval can now take two chars as arguments.
