README.md has some typo's

[RandyO-QL]

under the "recovery" section...

1. "factgory" is mis-spelled.
2. The command line at the end should refer to "tinyfpga-programmer-gui" not "tinfpga-programmer-gui".
3. It would also be nice to mention the pre-requisites for recovery, with links to the correct repo's and/or instructions for installation/recovery, such as
   a) install python3 (either under windows or ubuntu/linux)
   b) install the tinyfpgab package for python
   c) obtain a jlink or jlink-compatible pod
   etc.
