[LINTER] Add a linter to replace unsigned char with uint8_t
This is a recurrent issue in reviews, this diffs provides an autofix
linter for this.
It is named afted stdint so that other conversion can be lated added if
arc lint --everything # No warning
Edit src/init.cpp to add the line:
unsigned char foo;
anywhere in the file, then run:
arc lint -- src/init.cpp
The linter should catch the line and suggest a fix.
