Quickly get sweep numbers without generating sweep table

[kasbaker]

Overview:

Generating the sweep table can take a long time. For fast plotting, all you need is sweep_data for each sweep you want to plot. Adding EphysDataSet.sweep_numbers as a property that returns EPhysDataSet._data.sweep_numbers allows you to map EPhysDataSet.get_sweep_data onto the sweep_numbers you wish to plot.

Addresses:

This is a small addition so no issue was created on GitHub

Type of Fix:

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing
  functionality to not work as expected)
• Documentation Change

Solution:

Adding sweep_numbers as a property avoids accessing ._data, a protected attribute of this class.

Changes:

Just these lines added to ephys_data_set.py

    @property
    def sweep_numbers(self):
        """ Returns array containing all sweep numbers in this data set.

        Returns
        -------
        sweep_numbers : numpy.ndarray
            Array containing all the sweep numbers

        """
        return self._data.sweep_numbers

Validation:

Tested in a scratch file:

from ipfx.dataset.create import create_ephys_data_set

data_set = create_ephys_data_set(r"path/filename.nwb")
print(data_set.sweep_numbers)

Prints an array of sweep numbers as expected
