Update Adafruit_MMA8451.h

Unprotected the readRegister8 method in Adafruit_MMA8451.h

Leaving this function protected makes it impossible to implement some of the key features in the chip. These methods are detailed in NXPs application notes .
For example, in AN4070 on page 11: clearing interrupts register flags is completed by a direct register read, and safely bit setting the MMA8451 control registers is completed by first reading the current register state, setting the relevant bits, and then writing the updated state.

If I have time at the completion of my project I would gladly add the features we're building into the main library, but for the time being, protecting readRegister8 makes many of the chips features unusable with this library's current state.

Any chance we can get this in?

Bump

Ideally, the missing capabilities would be provided by new public methods that then use the protected methods. Can you restate the issue in terms of missing capabilities? Like "enable free fall detection".

By restate, do you mean re-work the info in the PR, or update my PR with the missing functionality that I wrote as a private method in the library??

It'd be good to first open an issue to state the general problem. That would allow discussion to be had about approaches for solving. Then a PR could be made in that context.

Leaving this function protected makes it impossible to implement some of the key features in the chip.

What key features? Why are they needed? Example use cases also help - to demonstrate why the current library lacks the capability to support it.
