Verify correctness of data curated from Chopen

[gsarma]

We need to go through the spreadsheets in raw_data/ and confirm that it has been correctly curated from chopen.herokuapp.com. This should not be difficult and will probably take 5-10 hours maximum.

openworm_scholar and ion_channel_basic_list will be straightforward. The more involved task will be checking that each spreadsheet in detailed_channel_info is correct. Things to look for include checking that there are links to figures, JSON files for digitized data, and that the links at the end of the meta data section are correctly formatted with one link per cell. Any other sanity checks are welcome.
