15060d9c - Support the BrailleNote Touch and Brailliant BI 14 via the BrailliantB brailledisplayDriver (#8031)

Support the BrailleNote Touch and Brailliant BI 14 via the BrailliantB brailledisplayDriver (#8031) * Support for HumanWare Brailliant BI/B braille displays connected via Bluetooth when the protocol is set to OpenBraille. * brailliantB: Try a delay after connect, multiple init attempts and delays between attempts as recommended by HumanWare, as init can be quite flakey, particularly via Bluetooth. * Add support for the Brailliant BI 14 and BrailleNote Touch. * brailliantB: Change some key names and add comments about devices to key table. * hwIo.Hid: add a setOutputReport method which allows writing data with HidD_SetOutputReport as an alternative to WriteFile which may freeze on certain USB implementations. * Fix support for newer BrailleNote Touch devices via HID, by writing display cells with HidD_SetOutputReport rather than WriteFile which can block forever on these devices. * Mention BrailleNote Touch in the UserGuide under Brailliant BI/B Series, and BrailleNote Touch * Mention Brailliant BI 14 in userGuide * UserGuide: update key assignments for Brailliant BI/B and BrailleNote Touch, splitting them into tables for all models, and extra specific. * hwIo.Hid.setOutputReport: add debugging. * Change description of BrailliantB driver. * change time.sleep to waitForRead to not block IO thread. * Fix debug string. * BrailliantB braille display driver: use HidD_SetOutputReport for all HID devices supported by this driver. Not only does WriteFile block for ever with USB HID, but WriteFile simply does nothing at all for Bluetooth HID. * BrailliantB braille display driver: add some extra key assignments with space as not all displays have command keys. * Change waitForRead before retrying init back to a time.sleep for now. If it is truly needed we can add it back in in the Autio braille display detection pr.
