Compile failed of v0.5.0 on ARM Mac Osx #41

Hello there!

I'm trying to compile a project which depends on xlsxwriter version 0.4.0. I immediately encountered the problem addressed here so I have upgraded its version to 0.5.0.

The problem above has gone away but unfortunately I have another problem when trying to compile:

It seems to be another problem linked to ARM. The compiler suggests to import some additional crates in xslxwriter.

Thank you!

Please update Rust or try latest commit in github. std::ffi::c_char was introduced in Rust 1.64.0.
