Error: datetime inputs (?)

I set up an env as described in #7 and checked out the current master of CoMIK. Following the instructions, I get the following error with Matlab 8.6.0

```bash
>> comik_wrapper('config-comik.txt');
Starting parallel pool (parpool) using the 'local' profile ... connected to 5 workers.
Error using readFastaSequences (line 54)
Function is not defined for 'datetime' inputs.
