feature: swap from @dataclass to pydantic BaseModel (#238)

* feature: switch almost everything to pydantic BaseModel

* feature: swap more dataclasses over to pydantic models

* feature: use more model serializers to make data handle better

* bug: fix some serialization issues with `None` values

* bug: fix some initialization problems with miner mode config

* bug: fix new BOS+ pool parsing

* bug: fix new BOS+ board temperature parsing serialization error

* bug: more misc fixes with serialization, extra methods, and hashrate types

* bug: add explicit type conversions to hashrate types

* bug: fix epic pool URL parsing

* bug: fix positional args in hashboards

* bug: fix epic missing url scheme

* convert board temp to int
