Toggle progress bar for structures, per-structure

[HyperDashPony]

Describe the feature

I have a custom multiblock detector which isn't as strict as the structures in Patchouli because the multiblock uses stair-like blocks, which can have the same shape given multiple blockstates. It's confusing players because they'll place something that's visually correct, and correct according to my multiblock detector, but not according to Patchouli's structure. Could we have an option to disable the validation for a given Patchouli structure, so it's only a visual guide?
