* `frozenset`:
    * 요청과 응답에서 `set`와 동일하게 취급됩니다:
        * 요청 시, 리스트를 읽어 중복을 제거하고 `set`로 변환합니다.
        * 응답 시, `set`는 `list`로 변환됩니다.
        * 생성된 스키마는 (JSON 스키마의 `uniqueItems`를 이용해) `set`의 값이 고유함을 명시합니다.
* `bytes`:
    * 표준 파이썬의 `bytes`.
    * 요청과 응답에서 `str`로 취급됩니다.
    * 생성된 스키마는 이것이 `binary` "형식"의 `str`임을 명시합니다.
* `Decimal`:
    * 표준 파이썬의 `Decimal`.
    * 요청과 응답에서 `float`와 동일하게 다뤄집니다.

In essence, they are `[]byte` -> `[]byte, error` functions.

It is not possible to return *both* an error and a response.

Handlers are registered on the manager using `(*Manager).RegisterSingleHandler(id HandlerID, h SingleHandlerFn, subroute ...string)`.

The server handler function has this signature: `type SingleHandlerFn func(payload []byte) ([]byte, *RemoteErr)`.

Sample handler:
```go

from fastapi import FastAPI, File, UploadFile
from fastapi.responses import HTMLResponse

app = FastAPI()


@app.post("/files/")
async def create_files(files: list[bytes] = File()):
    return {"file_sizes": [len(file) for file in files]}


@app.post("/uploadfiles/")
async def create_upload_files(files: list[UploadFile]):
    return {"filenames": [file.filename for file in files]}


@app.get("/")
async def main():

                stub_frag_len = msg.length - 24;

                if ((off + stub_frag_len) > stub.length) {
                    // shouldn't happen if alloc_hint is correct or greater
                    byte[] tmp = new byte[off + stub_frag_len];
                    System.arraycopy(stub, 0, tmp, 0, off);
                    stub = tmp;
                }

                System.arraycopy(frag, 24, stub, off, stub_frag_len);
