Updated 010 Editor ADF binary template

[hop]

I find 010 Editor (Windows, Mac, Linux) useful for editing binaries. I switched to it from HxD because, when comparing binary files, it has a very useful "Byte by Byte (Simple)" mode, which doesn't get confused by sequences and just shows the individual byte diffs at each offset.

I noticed the AmigaDOS filesystem aware ADF binary template written by Volker Broemmel. I've updated it to add block checksum validation. I find this useful if I make a quick and dirty hack to an executable in a data block on disk and want to fix up the checksum quickly. When and ADF is opened, the output now reports any blocks with invalid checksums (and the correct checksum). This info is also displayed in the template variables view, making it easy to locate the checksum to fix.

There are probably many other ways to do this, but thought it might be worth adding for convenience.
