[1.3.0] - 2020-12-27

Clickable links to failed assertions!

Added

• atto_true() which simply maps to atto_assert() to have an opposite of
  atto_false() with consistent naming.

Changed

• The printed text in case of a failed testcase now combines the filename
  and the line together in the format like filename.c:42 with 42 being the
  line. This allows some IDEs to recognise it as a link to a specific code line
  and make them clickable for much easier testing and debugging.

Fixed

• atto_zeros(x, len) supports any kind of address as x, even non uint8_t*
  thus allowing to scan arrays of other integers or floats or strings for
  zeros without explicitly casting them. They are converted to uint8_t*
  internally.

• Replace Doxyfile with CMake building it instead. Add stricter options.
