feat: add hexadecimal number literal parsing to wren compiler Remove the TOKEN_HEXADECIMAL token type and isHexDigit helper, replacing them with a readHexDigit function and readHexNumber parser that directly converts hex literals to numeric values during lexing. Add a `number` field to the Parser struct to hold the parsed value, and include a test for invalid hex literal error handling.
