Drop support for R < 4.1.
Now all functions accept font family name. This
is to support TTC file properly, which contains more than one fonts. A
new function dump_fontdb()
is useful to check the actual
family name (and the weight and the style) to specify. They also accept
a file path, so the existing code should work, except when specifying
tolerance
without the named argument.
The minimum supported Rust version is bumped to 1.56.0 for the 2021 edition.
