Please document prevenance of bundled hex bootloaders

[Github-Home-User]

This repository includes very useful hex blobs of bootloaders other than ATTinyCore . Unfortunately the related documentation files don't state their versions, origins and licenses .

To remedy this, README.md and any bootloader-specific Markdown file should contain a clarifying statement such as (using lots of placeholder names):

The included XYZ bootloader binary blobs were built by SpencerKonde from source code in release 1.2.3 of the XYZ fork at github.com/deadguy/SuperXYZ These is licensed under the GPL version 2 .
The included XYZ bootloader upgrade binary blobs were built by Mrs. Konde from the included bootloader binary blobs and the wrapper program found in the file blah/bleh/blat_upgrade.c These are released under the LGPL version 2.1 (except the bootloader blob inside each).

OR

The included XYZ bootloader binary blobs were built by deadguy from unknown sources and included in the historic SuperXYZ_1.2.3.tar.gz with sha256sum 1234567890ABCDEF1234567890ABCDEF1234567890ABCDEF1234567890ABCDEF These were released under the FooBar binary license .
The included XYZ bootloader upgrade binary blons were built by deadgirl from the included bootloader binary blobs and released in the historic SuperXYZ_updater_1.2.3.2012june.tar.gz with sha256sum FEDCBA9876543210FEDCBA9876543210FEDCBA9876543210FEDCBA9876543210 These were released under the BarBaz binary license .

OR whatever else is the truth .
