v1.1.0

Features

• Added complexity error type.
• Added I/O error type.

Fixes

• Reworked file reading to a chunk-based mechanism that handles both seekable/unseekable inputs and prevents buffer overflows.
• Implemented depth counter to reject deeply nested source files via complexity error.
• Removed uint16_t typecasts on size_t operands which silently truncated and produced wrong bytecode, and added bounds checking against UINT16_MAX in emit_u16() and patch_jump().

Thanks to @skeeto for identifying these issues.
