Wit Bash Script Can't Handle Symlinks

[seldridge]

The bash magic used by the wit bash script to locate itself doesn't work if symbolic links are involved. This comes up if using something like GNU stow for local "package management".

The following works great on Linux, but will not work on OSX as there's no readlink -f for OSX:

script_dir="$(dirname "$(readlink -f "$0")")"

This may be resolved by #206 making Wit a pip installable package.

Schuyler Eldridge (@seldridge) you can now install via python3 -m pip install wit-sifive if you want to bypass the wit bash script
