Release v2.4.9-pre.1

This release changes the following battery device attributes into sensors:

• batt_charge_peak
• batt_discharge_peak
• batt_max_charge
• batt_max_discharge

These are listed as "nameplate" values in specs which implies static information, but it was noted that these values may change (Issue #495 and discussion #496). Values that are dynamic in their own right should be implemented as sensors. It's unknown if they are dynamic for all battery types or only some.

What's Changed

• Battery charge/discharge power as sensors by @WillCodeForCats in #501
