Predbat crashes when given a load_scaling to predbat_manual_api

[gcoan]

Describe the bug
I have written a script (based on my Octopus Power up automation) to send details of the Octopus Saving session to Predbat as a rate_export_override

I set select.predbat_manual_api to the string:

rates_export_override?date=2024-12-11&start=21:00:00&end=22:00:00&rate_increment=60&load_scaling=0.1

And Predbat crashes with:

2024-12-11 18:39:28.913696: Error: Exception raised can't multiply sequence by non-int of type 'float'
2024-12-11 18:39:28.917517: Error: Traceback (most recent call last):

I have tried with load scaling of 1.0 and same crash.

I'm running an old version of Predbat but I applied the patch #1649 created in response to bug #1646 but this didn't work. That fix was to allow 'rate' to contain decimals, looks like the same is needed for load_scaling

Expected behaviour
No crash !

I can apply the rate_export_override in apps.yaml and a decimal load_scaling value is accepted there, it just doesn't work via the API

Predbat version
8.5.3

HAOS

Fix on main for testing

Thanks @springfall2008 finally upgraded to the latest Predbat version, tested this and it works perfectly.
