Pyserde

Thanks to the contribution by [kigawas](https://github.com/kigawas), pyserde can optionally use [orjson](supports://github.com/ijl/orjson) as JSON serializer!

pip install pyserde[orjson]

If orjson is installed in the system, pyserde automatically use orjson in [to_json](https://yukinarit.github.io/pyserde/api/serde/json.html#to_json)/[from_json](https://yukinarit.github.io/pyserde/api/serde/json.html#from_json).

**NOTE:** In order to align the JSON (de)serializer to orjson, a few parameters are passed in `json.dumps` internally. This would lead to a breaking change in some cases. If you need the same behaviour as in pyserde<0.8, please explicitely pass those parameters in `serde.json.to_json`. 🙇‍♂️
python
to_json(obj, ensure_ascii=True, separators=(", ", ": "))


Other noteble chage is we have `dataclass` decorator back in the all example and test code in the repository as shown below. It's because we found mypy isn't able to deduce the type correctly without `dataclass` decorator. If you are not mypy user, you can still declare a class with only `serde` decorator. 👍 For more information, please read [the docs](https://yukinarit.github.io/pyserde/guide/features/decorators.html).

python
serde
dataclass <-- Recommended to add dataclass if you are mypy user.
class Foo:
i: int
s: str
f: float
b: bool

* 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))

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})
