Support PPE profiling for Zip

[KantaTamura]

This PR resolves the Zip task in #258

Sample program to check tracing

import json
import pytorch_pfn_extras as ppe

from pfio.v2 import Local, Path, from_url
from pfio.testing import ZipForTest


def p():
    tracer = ppe.profiler.get_tracer()
    tracer.clear()

    zipfilename = "test.zip"
    data = dict(
        foo = b'foo',
        bar = b'bar',
        foobar = b'foobar',
    )
    file = ZipForTest(zipfilename, data)

    with from_url(zipfilename, trace=True) as fs:
        for name in fs.list(recursive=True):
            with fs.open(name, mode='rb') as fp:
                tmp = fp.read()
                assert file.content(name) == tmp

    state = tracer.state_dict()
    keys = [event["name"] for event in json.loads(state["_event_list"])]
    print(keys)

    w = ppe.writing.SimpleWriter(out_dir="")
    tracer.initialize_writer("trace_zip.json", w)
    tracer.flush("trace_zip.json", w)


p()

LGTM. Thanks!
