[Feature Request] Add ability to merge 2 vrcx databases

[AshtonSparx]

Explain in detail what your suggested feature would be used for.
I recently got a new boot drive and had it cloned, was having some issues so cleaned installed windows but forgot to backup my db. So i went 2 weeks without my main db but kept building the new one. I got a m.2 to type c to get my old one back but would like to merge them.

Describe how it would look if it requires a UI.
Add it as an advance feature with fat warnings and possibly auto generate a backup before performing the merge. Drag the extra database that you'd like to merge into current.

Explain why people would want to use it.
For people with situations like me. Or people with multiple devices perhaps.

Merging VRCX databases is not exactly a progress that can be done automatically, even with "fat warnings" this would be a lot of work for a feature that will only work around 10% of the time (with really small vrcx databases all under 10MB.
