Description

This pull request adds the environment variable PAPI_ALLOW_UNVERIFIED_EXPANSIONS.
It allows overriding the option set in the config.yml.

Accepted values are (case-insensitive) true, yes and 1 to allow expansions or false, no and 0 to forbid them.
If the environment variable is not set or the value is not valid, the value specified in the config.yml will be used.

If the value is set to true unverified expansions will be allowed (case-insensitive), if it is set to any other value, unverified expansions will be forbidden.

Nice idea, tho I personally feel like supporting all these specific options for what is basically true/false is not needed.
Just allow true false and then use env.equalsIgnoreCase("true") to check.

That would also be ok with me, I could make the change to that if requested

There is also this shortcut https://docs.oracle.com/javase/8/docs/api/java/lang/Boolean.html#getBoolean-java.lang.String-
And I agree with Andre, true and false are enough.

That method is just return value.equalsIgnoreCase("true"); xD
