Prevent lyrics filter for links to VHV

[craigsapp]

Example: https://polishscores.org/?id=pl-kk--kk-i-482--002-004

When the lyrics extraction analysis is active:

Clicking on the H button in the navigator opens the score in VHV:

https://verovio.humdrum.org/?file=https%3A%2F%2Fhumdrum.nifc.pl%2Fpl-kk--kk-i-482--002-004.krn&filter=lyrics

But there is no lyrics filter available in VHV, so a warning is given:

Prevent the lyrics tool from being added to the VHV URL.

Or alternatively, implement a lyrics tool in humlib. (Currently the lyrics analysis is cached on the data server and the tool is written in PERL connecting several Humdrum tools together).

Somehow not working again (or maybe lyrics filter added through some other path):

https://verovio.humdrum.org/?file=https%3A%2F%2Fhumdrum.nifc.pl%2Fpl-wn--mus-iii-86-055.krn&filter=lyrics

When clicking on the H button in the navigator toolbar on this page:

https://polishscores.org/?id=pl-wn--mus-iii-86-055
