component that request github server to get the last commit's comment for a specific file

i've just made this component :

a component that request github server to get the last commit's comment for a specific file

i've put on my github several scripts and i wanted to check if i use the last one on my computer.

When i commit on github i use comment's like "v0.5 blabla".

so when in grasshopper and i input the name of my script i get the last comment made

    Args:
        github [STR] : name of the github repository to request USERNAME/REPO_NAME
        script [STR]: name of the script you re looking for
        check [BOOL]: do the check?
        authorization [BOOL] : does it need authentification?
        token [STR]: the token for authorization
    Returns:
        version: the commit's comment

Limitation :

API rate limit can be exceeded, but here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.
https://developer.github.com/v3/#rate-limiting

It doesn't use the search api of github, maybe can be optimized?
