Document elf2tag script

[ndim]

This aims to add documentation to the elf2tag script (installed to $(bindir) by default):

• Add -h and --help argument handling to print the usage information.

• Add a very basic man page elf2tag.1.

  Some distributions encourage having man pages (e.g. Fedora), some other distributions require a man page for each executable in $(bindir) (e.g. Debian).

  It makes sense to concentrate this documentation effort at the place common to all distributions, i.e. upstream, i.e. here.

TODO:

• Build elf2tag.1 from elf2tag.1.adoc using the update-elf2tag-manpage script as git precommit hook, CI command, or buildsystem command, or just commit elf2tag.1 without elf2tag.1.adoc and update-elf2tag-manpage (like the avrdude.1 file)?

• Is the example command with avrdude disasm accurate?

Cool idea!

Does this need any additions?
