Add fixture 'Varytec Giga Bar Frost Pix 8 RGB'

[luc122c]

Hi @FloEdelmann! This PR supersedes the automatic one (#2842) as I have added the links that I was not able to add when importing the QLC+ file. As per your issue #2429, I've completed the following checks:

Checking whether at least 3 links are present. Otherwise, finding suitable links.

• link to a manual PDF containing all DMX modes

• link to a product page on the official manufacturer website

• link to a YouTube or Vimeo video that showcases or explains the fixture

• Checking whether all DMX modes from the manual are included in the fixture definition.

• Checking whether all DMX modes' channels from the manual are included in the fixture definition.

• Checking whether all DMX channels' capabilities from the manual are included in the fixture definition.

For the fixtures passing these tests, these are some common tasks that often need to be fixed:

• replace capability type StrobeSpeed with ShutterStrobe where that one fits better
• replace capability type Generic with Maintenance where that one fits better
• rename modes that have no name in the manual to the usual 5-channel/5ch format
• link to an English manual / product page (if one exists) instead of one in another language
• Pull requests with these fixes against the original fixture pull requests

I'd much appreciate if you could close the automatic PR and merge this one. I have also emailed you about helping to clear the backlog of new fixtures.

Thanks for the fixture definition! I already improved it a bit, but I still have some open questions. We can turn them into helpWanted messages though if you don't have access to the fixture.

So there are multiple programs here? Can you tell at which DMX values the effects change?

[luc122c]

According to the 'Operating mode ‘Built-in automatic show’' section of the manual, there are multiple shows (Pr01 - Pr21) and options to set a 'background colour' and a 'hopping colour'. However, these options only seem available when the fixture is not being DMX controlled.
In DMX 2ch mode, the function of Ch2 changes depending on the value of Ch1. This was difficult behaviour to program in QLC+. I had to use the Aliases feature which was new to me. Ch2 only changes the speed, there is no mention of being able to select a program. I'm therefore not sure if it cycles through Pr01 - Pr21 or just sticks to one.
I can test the fixture at the weekend and report back.

Okay, I added helpWanted messages, so we can merge this now. Please open a new PR with the fixes when/if you can! :)
