Add GPX filters

[inode64]

I am currently developing a module in Go (https://github.com/inode64/gotrackmaster) to optimize, filter and improve GPX tracks and I found your project which is very interesting
And I would be interested in helping and adding the algorithms (remove noise, Gaussian filters, remove stops, clean traces, etc.) that I have developed to add to your tool.

How could I carry out this collaboration to bring it to a successful conclusion, if you can give me some guides (names of variables, a library, etc.)

All the best
