Pait[0.9.0] Support custom enable `TipException` to wrap exceptions that occur in pait

TipException can be a good indication to the developer of which route the current error is generated by, as follows:

from starlette.responses import JSONResponse

from pait.app.starlette import pait
from pait.field import Header


@pait()
def demo(token: str = Header.i()) -> JSONResponse:
    return JSONResponse({"token": token})


if __name__ == "__main__":
    import uvicorn
    from starlette.applications import Starlette


    app: Starlette = Starlette()
    app.add_route("/api/demo", demo, methods=["GET"])
    uvicorn.run(app)

Although the original exception can be obtained through TipException.exc, in some cases it is necessary to get the original exception directly or to be able to use a custom TipException.
