Change import of compress

[nikhase]

from tspreprocess.compress.compress import compress looks very redundant.

I would prefer from tspreprocess.compress import compress. One could get rid of the intermediate folders and have all files on the 2nd level?

One could also think of renaming the compression function such that it does not coincide with the module name, e.g. to compress_ts.

this is easy. just import the method in the respective init.py to move methods from one namespace to another. we can do that later once we have more code and an indication into which direction we are going with tspreprocess
