Add `setProgress()` back in for the single-threaded version

[JellyBrick]

Is your feature request related to a problem? Please describe.
According to this documentation, setProgress() appears to have been removed in 0.13 (in favor of multitasking).
But if I'm using the single-threaded version, the issue with multitasking is not an issue at all.

Describe the solution you'd like
Add setProgress() back in for the single-threaded version.

Describe alternatives you've considered
Use 0.12 instead of 0.13.
But I don't want to use 0.12 anymore (it's more complicated to use than 0.13)

Additional context

It is expected that this API will be re-added in v0.14, both single-threaded and multi-threaded versions.
