Singer Bulk Cache Generation

Currently when you initially use a Singer for the first time the project will render significantly slower as it’s also generating cached files for each of the samples as they’re needed.

An option under the Right-Click context menu to, in bulk, cache all of that singers audio so that they can render faster right from the get-go when used in future would be quite useful.

It would also be especially nice if you could opt in when initially installing a singer to have it do this as well during that process.
