[PATCH -perfbook] sytleguide: Upgrade references to NIST style guide as bibliography

[Akira Yokosawa <akiyks@xxxxxxxxx>]

The NIST style guide was referenced as URL links in footnotes.
Those links got broken due to the update of SI standards in 2019.

Fix this by adding proper BiBTeX entries in standard.bib and citing them.
Also make NIST's other cheat sheets and JEDEC's "mega as a prefix to units"
dictionary page as bibliography entries.

Hi Paul,

I put the bib entries in standards.bib, which might or might not
be the right place.
If you have more suitable place in mind, please let me know.

        Thanks, Akira
