Pyserde

* fix: Optional in custom class deserializer ([181b2f1](https://github.com/yukinarit/pyserde/commit/181b2f1))
* fix: raise SerdeError from serde's APIs ([76b0aee](https://github.com/yukinarit/pyserde/commit/76b0aee))
* pyserde (de)serialize method used to raise various Exceptions such as KeyError. pyserde always raises SerdeError since v0.7.0
* core: using black formatting only if debug is enabled ([e596a84](https://github.com/yukinarit/pyserde/commit/e596a84))
* feat: Add _make_serialize and _make_deserialize ([a71c5d5](https://github.com/yukinarit/pyserde/commit/a71c5d5))
* feat: Implement Union tagging system ([c884dc4](https://github.com/yukinarit/pyserde/commit/c884dc4))
* This will change the default tagging for dataclasses with Union from `Untagged` to `ExternalTagging`. **This may break the existing code**, so please be aware if you use dataclasses with Union. For more information, check [the documentation](docs/features/union.md)
* build: Update mypy to workaround typed_ast error ([0ea33a7](https://github.com/yukinarit/pyserde/commit/0ea33a7))

* feat: Add serde decorator ([523dc9c](https://github.com/yukinarit/pyserde/commit/523dc9c))
* feat: Add serde field function ([488bf00](https://github.com/yukinarit/pyserde/commit/488bf00))
* feat: Add serde_skip_default field attribute ([0f0b212](https://github.com/yukinarit/pyserde/commit/0f0b212))
* feat: Automatically put dataclass decorator ([2f0cf01](https://github.com/yukinarit/pyserde/commit/2f0cf01))

With `serde` decorator and `field` function, you can declare pyserde class more easily.

python
from serde import serde, field

serde
class Foo:
a : List[str] = field(default_factory=list, skip_if_false=True)


The declaration until v0.5.3 still works.

python
from dataclasses import dataclass
from serde import serialize, deserialize

deserialize
serialize
dataclass
class Foo:
a : List[str] = field(default_factory=list, metadata={'serde_skip_if_false': True})

* feat: Add more dataclass Field's attrs to Field ([7b57c53](https://github.com/yukinarit/pyserde/commit/7b57c53))

* refactor: Remove type references from SerdeScope ([bdd8784](https://github.com/yukinarit/pyserde/commit/bdd8784))
* refactor: Speficy correct type bound for serde.core.fields ([c3b555c](https://github.com/yukinarit/pyserde/commit/c3b555c))
* fix: Add types in typing module to scope ([e12e802](https://github.com/yukinarit/pyserde/commit/e12e802))
* fix: Never use default value for from_tuple ([3ce4f6b](https://github.com/yukinarit/pyserde/commit/3ce4f6b))
* fix: Use default value only if key isn't present ([3fa4ab6](https://github.com/yukinarit/pyserde/commit/3fa4ab6))
* Fix typo in README ([5f957d0](https://github.com/yukinarit/pyserde/commit/5f957d0))
