write method param const-ness

[yilungao]

fix https://github.com/adafruit/Adafruit_FRAM_SPI/issues/25

• Describe the scope of your change--i.e. what the change does and what parts of the code were modified. This will help us understand any risks of integrating the code.

Scope: added const keyword to void Adafruit_FRAM_SPI::write(uint32_t addr, const uint8_t *values, size_t count)

• Describe any known limitations with your change. For example if the change doesn't apply to a supported platform of the library please mention it.

This change is dependent on the pull request on the underlying lib Adafruit_BusIO. Tested with ESP32 DevKitC (espressif) and the Adafruit SPI Non-Volatile FRAM Breakout - 64Kbit / 8KByte (MB85RS64V).

Thank you!

hiya! thanks so much for submitting a PR! we can review & merge PRs once they have passed continuous integration (CI). that means that code compiles cleanly for all tested platforms, is clang formatted so we maintain the same text formatting for all new code, and is doxygen documented. if your code isnt passing, check the CI output (click on the red X next to the PR to scroll through the log and find where the error is

here is a tutorial on doxygen: https://learn.adafruit.com/the-well-automated-arduino-library/doxygen

and clang-format: https://learn.adafruit.com/the-well-automated-arduino-library/formatting-with-clang-format

and overall how to contribute PRs to libraries: https://learn.adafruit.com/contribute-to-arduino-with-git-and-github

once you get that green checkmark that indicates CI has passed, please comment reply to this post so we know its time for another review (we may not get notified on CI pass and miss that its time to look!)

this probably needs to wait a few days for new version of BusIO released. Since CI runs based on the released lib. Please be patient in the meanwhile
