Poor man's volume profile

This is an attempt to get something more or less similar to the volume profile for free.

The code is generated using a template. To change the settings, you may need to regenerate the code. The code has a link to the repository with the template.

Notas de prensa:

Volume clusters (those called historical blocks) have been moved to a separate study, see "Poor man's volume clusters".

Study has been significantly optimized. Now you can set the profile size up to 500 bars (limit can be lifted if you change max_bars_back in the source code).

Correct way (I'm sure of it) to calculate row value. It could be wrong.
