mkindexp error on soft masked genome file

[f-heeger]

lambda mkindexp -d trial_lambda_genome_lower.fasta where trial_lambda_genome_lower.fasta is the attached fasta file, which contains lower case letters (like a soft masked file) gives the error:

Detecting database alphabet...

ERROR: The following unspecified exception was thrown:
"Your query file contains illegal characters in the first sequence.
"
If the problem persists, report an issue at https://github.com/seqan/lambda/issues and include this output, as well as the output of lambda2 --version, thanks!

I assume this is connected with dropping support for masking, which I don't have an opinion on, but it would be nice to still be able to use soft masked files (maybe give a warning that masking is ignored)

This happens with the pre-compiled linux binaries of version 1.9.4

confirmed

should be fixed in current master
