[Enhancement] Explore scope of further speeding up

[Udayraj123]

Requirements

The current code of OMRChecker's core algorithm, does not make use of any optimisations. One can explore the scope of optimising the whole flow and reach best speeds feasible.

Ideas

• Add Simple threading to speed up the checking across files parallely.
  • Found a simple example in practice here: https://github.com/GregoryCMiller/omr/blob/master/omr/omrcmd.py#L34
• Use pyrDowns and pyrUps to optimise the image transformations.
• More ideas? Can discuss in the comments.

This idea is related to this task

Sharing one more example that checks if multithreading is enabled to avoid uncaught errors
