Added Python script for verifying SHA256 checksums of files in a directory, which can run on multiple platforms. Improved the formatting of the output results for better readability.

update to the readme for improved readability and to explain the usage of the python checksum verification script

I've extended the script based on suggestions by @prusnak

The script now checks the available RAM, is there is enough to check the file at once it will do so. If not the file is read in chunks.

small change so that the available ram is checked and not the total ram

… is available

based on suggestions from @prusnak i removed the part of the code that checks whether the user had enough ram to read the entire model at once. the file is now always read in chunks.

quick fix to pass the git check
