Source.py::tesscut_dir() needs to test for the need to os.mkdir $HOMEDIR/.eleanor

[texadactyl]

Running the quickstart sample .....

import eleanor
import numpy as np
import matplotlib.pyplot as plt

star = eleanor.Source(tic=38846515, sector=1, tc=True)

gets the following error:

source.py:396: UserWarning: Warning: unable to create .. Downloading TessCut to the current working directory instead.
  'working directory instead.'.format(download_dir))

In Source.py::tesscut_dir() the download directory is implicitly created as follows at line 396:

download_dir = os.path.join(os.path.expanduser('~'), '.eleanor/tesscut')

If directory $HOMEDIR/.eleanor does not yet exist, it must be created (os.mkdir) before executing that statement. Otherwise, the downloaded file winds up in the current directory (not desirable).

Running on Xubuntu 18.04.3.latest with Python 3.latest.

Something simple like this would work:

from os.path import expanduser
DIR = expanduser("~/.eleanor")
if not os.path.exists(DIR):
    try:
        os.mkdir(DATA_DIR)
    except Exception as err:
        oops("main: Cannot create directory {}:\n{}".format(DIR, str(err)))

For whatever it is worth, I just ran into a surprising tensorflow 1.14.0 fatal anomaly (not an eleanor issue). See tensorflow/tensorflow#17411 for description and work-around.

A one-line program produces it:

import tensorflow as tf

like in targetdata.py::psf_lightcurve()

This should be sorted in the most recent version 1.0.0, thanks for pointing it out!
