V1.10: UI Upgrades and async optimisations

In this update I have added parallel optimisations to decrease the process time.

I have also added some UI upgrades such as a time to completition label, progress bar and greying out of buttons when and not needed.

The cancel button also works now.

One known bug is whenever there are multiple instances of excel open when the program is running there is a "object is in use elsewhere bug" this can either be referring to the excel instance or the image itself, one fix is to open cmd, type in "taskkill /f /im excel.exe" and moving the image to a new folder and restarting the program

I hope to have this bug fixed in V1.11

Working Application

V1.0 of ExCell Art of pixel Art applications.

Just choose an input image and an output directory and the magic is done for you!

Warning, there will be bugs so if anything doesn't work for you just leave a bug report in issues and I will try to get it working.

Best of Luck- James
