#78 reduce filesize of large test files

This PR reduces the size of the files stored in git-annex by reducing the recording time of large files. This concerns the following formats and files:

• Neuralynx/Cheetah_v5.6.3/original_data/*.nvt
• Neuralynx/Cheetah_v5.6.3/plain_data/CSC*.txt
• Neuralynx/Cheetah_v5.7.4/plain_data/CSC*.txt
• Neuralynx/Cheetah_v5.5.1/plain_data/Tet*.txt
• neuroshare/Multichannel_fil_1.mcd
• tdt/aep_05/Block-1/aep_05_Block-1.tev
• tdt/aep_05/Block-1/aep_05_Block-1.tsq
• tdt/aep_05/Block-2/aep_05_Block-2.tev
• tdt/aep_05/Block-2/aep_05_Block-2.tsq
• spikeglx/Noise4Sam_g0/Noise4Sam_g0_imec0/Noise4Sam_g0_t0.imec0.ap.bin
• neuroscope/test1/test1.dat (see https://gin.g-node.org/NeuralEnsemble/ephy_testing_data/pulls/80)

Update

The current changes reduce the repo size from 1.3Gb to 1.1Gb More potential files for shortening

Update

On the Neo side this PR depends on https://github.com/NeuralEnsemble/python-neo/pull/1122

@sprenger Can you also add https://gin.g-node.org/NeuralEnsemble/ephy_testing_data/src/master/neuroscope/test1/test1.dat to the list? 37 MB instead of < 10MB, super simple binary blob format and the # of frames is not encoded in the header .xml

Progress update: The neuroshare and tdt files can not be easily shortened, as the first ones has no specifications and is read via a dll and the second ones has an interdependency between tsq and tev files. I will try to replace these with smaller files from other datasets.

Update: Neuroshare has been replaced by another file with much smaller size.

@samuelgarcia, I moved the remaining files to be reduced to a new issue (#83), so we can merge this PR now. Currently this reduces the size of the repository to about 1.3GB to 900MB.

I ran the Neo testsuite locally with the new set of files and everything seems to work when using https://github.com/NeuralEnsemble/python-neo/pull/1122. Could you merge https://github.com/NeuralEnsemble/python-neo/pull/1122 and then this PR here?

Hi @samuelgarcia, thanks for merging the linked neo PR. Can you review and merge this one next? Not all files in the list have been reduced, but I think we should merge this rather sooner than later. All other files have been listed in (#83).
