release: cut 1.0.1

[davydog187]

Summary

Prepares the v1.0.1 patch release.

• Bumps @version to 1.0.1 in mix.exs
• Adds the 1.0.1 CHANGELOG entry (and compare link)

Contents

One change since v1.0.0:

• lexer/parser: report non-ASCII unexpected chars as valid UTF-8 #395 — lexer/parser now report non-ASCII unexpected characters as valid UTF-8. Multibyte characters were matched a byte at a time, mangling error messages; the lexer now carries the full codepoint (Unexpected character: … (U+XXXX)), reports genuinely invalid UTF-8 lead bytes separately as Invalid byte 0xXX, and Lua.Parser.Error.to_map/1 scrubs invalid bytes so every field is Jason.encode!/1-safe.

Post-merge

Tag v1.0.1 and mix hex.publish.
