rustdesk1.4.8

Modified version 1.48 of Rustdesk using the proposed changes made by @supemeko here:
rustdesk@4432a3f

All credit goes to @rustdesk for the original program and to @supemeko for the patch!!
I only tested the Windows x64 and rustdesk-1.4.8-x86_64.deb (with linux mint 22.x) versions yet. All other binaries are untested, so use them at your own risk !!
