What does happen?

I'm working on DuckDB bindings for the Crystal language using the C API when I got the following error:

Undefined symbols for architecture x86_64:
  "_duckdb_bind_uint16", referenced from:
      _*DuckDB::Statement#bind_arg<Int32, UInt16>:Nil in D-uckD-B-5858S-tatement.o
  "_duckdb_bind_uint8", referenced from:
      _*DuckDB::Statement#bind_arg<Int32, UInt8>:Nil in D-uckD-B-5858S-tatement.o

After a while I finally noticed a small typo on the C header file, as the binding functions for both uint16 and uint8 expect signed integers instead of unsigned ones as parameters.

What should happen?

The C API header binding functions should contain the expected signatures, i.e., uint8_t and uint16_t instead of int8_t and int16_t.

Environment (please complete the following information):

• OS: MacOS 11.5 (Big Sur)
• DuckDB Version 0.2.8
