improvements to set_authorization function

[AndrewIrwin]

It would be great to enhance the set_authorization function to look in standard places for an API key, to encourage users to not put API keys in their source file and then accidentally distribute those keys.

For example, I put the following in ~/.Renviron:
CMAP_PAT_USER=xxxx

Then I use
# readRenviron("~/.Renviron") # put the API key in ~/.Renviron as CMAP_PAT_USER=XXXX
set_authorization(cmap_key = Sys.getenv("CMAP_PAT_USER"))

credentials::set_github_pat has other ideas as well.

Or perhaps just suggest this pattern in the documentation?

Oops, we missed this, sorry! Your mainly suggesting a documentation update, right?

[AndrewIrwin]

A documentation change would be good. Also possible would be setting the default value for cmap_key to read the environment variable.

I see for example in the code Ginger showed in her talk this morning had a space for a hard-coded API key, although she didn't show it. Including the key in your code means its only a matter of time before someone / anyone publishes a key or commits it somewhere. So its a nice practice to encourage people to not put the PAT / API key in their code.
