suggested edits for MrC Converter Suite readme

Your Windows instructions are not sufficient/accurate about path/directories if one is using OneDrive to re-direct their Desktop folder to the cloud.
Second, your examples of command-line might point out that using the Converter's file extensions is not proper form. It was a crazy assumption I made to add the ".pm" to the string, but it does cause the command to error.
Third: when installing the per-requisite Strawberry Perl, I instinctively tried to avoid installing same to C:\, only to find that Strawberry Perl won't accept a file path with spaces (C:\Program Files).
Thank you for your efforts and program.
