Support minimiser file on update insert

[pirovc]

Currently, the update insert does not support minimizers.

Likewise, if the update insert is done directly based on sequences.

Should work on my dynamic branch.

See commit message:

Caveats:
* All files for a batch insertion must be either sequence or minimiser
  files (bin_validator).
* k-mer and window size are not checked against index.

The first one is the same as with build. If need be, I can adapt that to allow mixed batch inserts. Currently, only the validation is preventing that; the insert code actually supports reading mixed sequence and minimiser files.

The second one is update insert specific. The minimiser files should use the same w and k as the index. Otherwise, search might not find bins inserted through minimiser files, because search uses w and k from the index.

Thanks. I re-tried the first example and now I get the following error with update insert:

terminate called after throwing an instance of 'std::logic_error'
  what():  The size of a bin must be > 0.

I'm using only minimisers and the w,k sizes match.
