parser for columnar annotation files like disorder predictions

A number of bioinformatics analysis services produce files that look something like :

# header stuff
ASEQUENCETHATWASPREDICTEDN
# some separator
#optional header
<position> <residue/base> <Number> <Symbol>

A new jalview.io parser could be created for this kind of 1D annotation format - enabling data to be directly imported from a number of per-sequence analysis programs.
