[amsat-bb] Fox-in-a-box download is updated

[Burns Fisher]

The download website, http://burnsfisher.com/AMSAT/FoxInABox now contains
the SD card image, FIAB-distro8-V1.08w.zip.  This file, when unzipped and
written to a 16Gb SD card will give you the latest software for FoxTelem
and will run on a Raspberry Pi 4.  This is an image of the same SD card
that has been shipping from the AMSAT store for several weeks.  (It should
work on an 8Gb card as well with less room to spare of course).

1.08w has a few fixes from 1.08r, the previous download version, and will
capture data a bit better.  Remember that the later 1.08 versions
(including r and w) know how to switch bands between listening on VHF and
UHF based on which of Fox and Husky satellites are overhead at the time.

We expect HuskySat to be released from the ISS relatively soon, so be
prepared!
