JalviewLite can't import sequences with ID descriptions containing angle brackets

Reported by Kazutaka Katoh - sequence ID lines with angle brackets cause VARNA exceptions to be thrown. Most likely cause is angle-brackets match the jalview.io.Identify pattern for an RNAML file, so Jalview attempts to call the VARNA rnaml parser.

Importing this:

>aseq 5 soso <>[some reference]
MSTFMSTF

Results in the following stacktrace:
