The serialisation of soc to SoC should not occur in camel case if it is existing at the beginning of a field

consider this fictional field:

@dataclass
class Bidirectional:
    soc_battery: Optional[str] = None

when serialised;

results in SoCBattery when it should be socBattery

`@dataclass
class Bidirectional:
soc_battery: Optional[str] = None

def test_serialise():

expected = {'socBattery': None}

assert snake_to_camel_case(asdict(Bidirectional())) == expected`

test_v2x serialisation.py:38 (test_serialise)
{'SoCBattery': None} != {'socBattery': None}
