[Feature] Single-relic OCR tool for importing

[fribbels]

Motivation

Current we only have the Full-account import (takes a while), and the relic scorer import (limited to 24 characters, have to manually assign relics to characters)

Objective

Build an OCR tool on the optimizer site where users can paste their clipboard screenshot of a relic and have it OCR'd and imported.

Other thoughts: there's two different relic displays, handle both?

Having some problems with number of substats for 3*, 4* and 5* differences. For 5* the OCR is working, but not for lower rarities. Will think a way to fix it in the future.

Deprioritizing this one a bit, Reliquary and the relic modal changes have made this less important
