Pull in `readOne` and `readMultiple` from

[kenjdavidson]

The following fork has some helper methods that seem promising:

https://github.com/kenjdavidson/react-native-bluetooth-classic/commit/99b785fb239e993ed0776df71c4e7d96ca892456

• readOne()
• readMultiple()

although they are shortcuts to bypass the whole string delimiter and get it working like a ByteArray. Both of which can actually by done in combination with:

• available()
• read() in a loop based on available()

These are also not implemented on the IOS side in this fork, that will need to be done.
