get_waveform_data creates incorrectly named mseed files

[chrislat]

Using the code in the README file:

import datetime
from quakesaver_client import QSLocalClient

client = QSLocalClient()
sensor = client.get_sensor("qssensor.local")

tmax = datetime.datetime.utcnow()
tmin = tmax - datetime.timedelta(minutes=10)
file_path = sensor.get_waveform_data(tmin, tmax)

The following file is produced: "QS.IXNBX._2023-05-03T07/45/43.014334-2023-05-03T08/12/38.459333.mseed" instead of: QS.IXNBX._2023-05-03T07/45/43.014334-2023-05-03T08/12/38.459333.mseed

Notice the double quotes in the file name.

Shouldn't be an issue anymore when #16 is merged.
