v1.0.7 - Now with a simple BLE example - beta

This is a non-standard release. The target is the core-ble branch to provide an Arduino-based BLE example. There is little to no extensibility and the BLE functionality will likely be overhauled in the near future. Enjoy it while it's hot!

Also includes some other worthwhile upgrades that will be sticking around like:
PDM microphone library
Ambiq Secure Bootloader timeout increase for handling larger file uploads
