v1.0.0

### Initial Version v1.0.0
1. Add support to SAMD51 family such as Itsy-Bitsy M4, etc.

Library is based on and modified from:
1. [Cristian Maglie's FlashStorage](https://github.com/cmaglie/FlashStorage)

The FlashStorage library aims to provide a convenient way to store and retrieve
user's data using the non-volatile flash memory of microcontrollers.

The flash memory, due to his properties, is generally used to store the firmware
code, but it can also be used to store user data.
