[Breaking] Refactor NimBLEUUID.

Browse Source 
* msbFirst parameter has been removed from constructor as it was unnecessary,
caller should reverse the data first or call the new `reverseByteOrder` method after.
* `getNative` method replaced with `getBase` which returns a read-only pointer to the UUID size underlying.
* Added `reverseByteOrder` method, this will reverse the bytes of the UUID, which can be useful for advertising/logging.
* Added `getValue` method, which returns a read-only `uint8_t` pointer to the UUID value.
* Removed `m_valueSet` member variable, `bitSize()` can be used as a replacement.
* General code cleanup.
