Add comparison to SRA toolkit to documentation

[seandavi]

For all users, the standard has been to use the SRA toolkit. It would be great to have front-and-center documentation about how fusera differs, when fusera is preferred and why, and some use case translation from the sra toolkit to fusera (ie., how would one do a fastq-dump with fusera vs fastq-dump).

Passed along to SRA for consideration.

That is a good suggestion. We are low on docs and quick guides for the cloud access but documentation is being written currently. The short version for fusera vs sra-toolkit though is that fusera is typically giving you the submitted data format. So if it is already fastq there is no conversion required. If it isn't fastq then the user will need to convert the data as needed.

This is great feedback, @stineaj. I guess the two projects (fusera and sra-toolkit) are less related than I had thought.
