Some of that is waiting on #342

I have to insert some delays in the esp_loader_flash_defl_start() function in order to get it to work, otherwise it always fails with

Flash size detection failed, falling back to defaultError: COMMAND_FAILED
Cannot start flashing wifi

With the delays, it will fail if the wifi application firmware is written right before the filesystem with DEFLATE_ERROR.
If the wifi app does not have to be written (checksum matches, or is not present in the manifest) then filesystem flashing works. It behaves similar to the #259 (only works the second time you flash) but the errors are different, so I don't think it's the same issue.

The fix/workaround I found was to switch the order of the files in the json manifest. Then I can flash both the application and the filesystem.

I'm not comfortable with how fragile this is, but it's working every time with these changes. There must be some issue with the ESP loader changing state between non-compressed and compressed?

My plan to is to keep testing and make the file order change in the manifest generator.

I merged in more of #282 (skips Wifi modules without an error if not connected and reports it on screen)
