Failure to load timescale with builtin=False

See original GitHub issue

Trying to follow along with the example here to manually update the IERS file and load.timescale(builtin=False) appears to fail without attempting to download the file:

Python 3.9.0 (default, Nov 15 2020, 14:28:56) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from skyfield.api import load
>>> ts = load.timescale(builtin=False)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/brad/anaconda3/envs/test/lib/python3.9/site-packages/skyfield/iokit.py", line 354, in timescale
    with self.open('finals2000A.all') as f:
  File "/home/brad/anaconda3/envs/test/lib/python3.9/site-packages/skyfield/iokit.py", line 312, in open
    return open(path, mode)
FileNotFoundError: [Errno 2] No such file or directory: './finals2000A.all'

Based on the documentation, I expected this:

>>> ts = load.timescale(builtin=False)
[#################################] 100% finals2000A.all

A regular call to load.timescale() works normally.

Versions I’ve reproduced this error on:

Python 3.8.5, 3.9.0
skyfield 1.31, 1.32

Just tried that. Though I am embarassed for not having tried that sooner, it is a good type of embarassed. It worked of course!

Thank you for your generosity toward someone with far far less experience than yourself.

Just tested the new version and everything looks good on my end now. Thanks for the quick fix!
