BadUSB/BLE Updates

[emericklaw]

Proposed Changes

BadUSB/BLE

• Reduced default delay between keystrokes in USBHIDKeyboard from 25ms to 10ms
• Introduced caching mechanism for shift key mappings in USBHIDKeyboard.
• New commands:
  • WAIT_FOR_BUTTON_PRESS - pauses and prompts on screen for button press
  • ALTCHAR - used to convert alt character codes to keypresses eg ALTCHAR 65 will output A
  • ALTSTRING - converts the supplied string into alt codes to be sent to the device
  • STRING_DELAY - sets the key delay for the next command
  • DEFAULT_STRING_DELAY - sets the key delay for the rest of the script
• Updated display - top gives info about the file being run, status and runtime - lower section shows the commands being run
• Moved the BLE Name menu to the BLE -> Config menu since no one (including me) could find it
• Add warning for low key delay in BLE setup due to missing characters …

Other Minor Changes

• Added 'Back' button handling so the settings do not get cleared - there are many others dotted throughout the code, this covers ones in the Config menu
• Fixed some spelling mistakes which were not meant to have been in this PR

New Screen

Testing

I have tested on a few Bruce devices with no issues.

BadBLE was also tested, only issue is missing keystrokes if the connected device cannot keep up, there is a warning shown when launching BadBLE if the delay is lower than 50ms.

I have not tested using a CH9329, it should work.

Linked Issues

Fixes #1157

User-Facing Change

BadUSB/BLE is now runs a lot faster and has 5 new commands to bring it much closer to supporting the full range of Ducky Script commands.
