"BSD" is not a valid license identifier

[GaryJones]

In composer.json, the license is given as BSD, but this is not valid. The value should be one of the values from https://spdx.org/licenses/, and as can be seen, there are several variations of "BSD".

You're right! I was just trying to match the license included in the original repo, but this is the first time I've released something under that license and I didn't think to look for the specific one. It seems to be BSD-2-Clause.
