Hello,

some of the other BATS helper libraries have a load.bash helper file in the root of the repository.

• https://github.com/bats-core/bats-assert/blob/master/load.bash
• https://github.com/bats-core/bats-support/blob/master/load.bash

This makes it easier to include the library with bats_load_library:

bats_load_library has two modes of resolving requests:

1. by relative path from the BATS_LIB_PATH to a file in the library

2. by library name, expecting libraries to have a load.bash entrypoint

https://bats-core.readthedocs.io/en/stable/writing-tests.html#bats-load-library-load-system-wide-libraries

It would be great if we can add it for this library as well.
