Create overloads to allow float values to be saved in NVS

[SamAtBackbone]

Description

Added methods to get, get_or_set, and set float values to the ESP NVS system.

Motivation and Context

I needed to store float values and NVS only supports int/uint value storage at this time.

How has this been tested?

Storing and retrieving float values. Used logs to show the storage and retrieval process, also confirmed behavior of firmware to match stored values.

Logs from storage:

Logs from retrieval after hardware reset:

Screenshots (if appropriate, e.g. schematic, board, console logs, lab pictures):
