bug: Error with time series Normalization on Sienna Export

[ktehranchi]

Describe the bug
Error on Sienna TS export: We use a Normalization Factor: 'Max' for timeseries pointers, then multiply them by max_active_power through ("scaling_factor_multiplier": "get_max_active_power").

This will lead to errors with Timeseries which do not contain 100% capacity factor values.

Example:
TS value: 80
Max value of TS array: 90
Max active power: 100

TS value loaded to PSY: 80 / 90 * 100 = 88

@pesap Would be good to get your thoughts on this, since we'll have to align how we export data with how we parse data from either plexos/reeds.
