Soda vending ads and goodbyes v2

[Alpaccalypse]

About the PR

Gives all branded soda vendors their own advertising and purchase chatter.

Why / Balance

All soda vending machines share the same set of adverts and goodbyes, this can get quite repetitive and doesn't always make complete sense for the specific drinks that were vended. This makes each branded machine have its own set of advertising and purchase dialogue.

Technical details

(v2 of a closed PR which was getting out of hand with Git Bash errors)

• Adds new .ftl files for each branded vendor
• Edits vending_machines.yml, goodbyes.yml, and advertisements.yml as well as cola.ftl and sovietsoda.ftl

Media

My favourite, thanks for the suggestion:

Requirements

• I have read and am following the Pull Request and Changelog Guidelines.
• I have added media to this PR or it does not require an ingame showcase.

Breaking changes

Changelog
None. Flavour/cosmetic, with no impact on gameplay.

Thanks for the PR!

I just had some brief nitpicks for the advertisements, and I'll be back later to review the rest.
