Break out binary name funtion to it's own function

Remove duplicate code. get_binary_name is now in the install script
Add some "version" checking to ftl download when using an alt branch, uses checksum
Greatly simplify update process. Source pihole-FTL version checker from basic-install.sh
Always run install script to finalise changes.
Install script now outputs versions after an update
(This is a Squash of previous work into one commit)
