JSFX export missing tanhf

[kartun83]

Code using "ma.tanh" exported to JSFX missing implementation for tanhf.
I was using web ide, so no idea what's version is that.

AFAICS tanh is not available in th JSFX language, documented here: https://github.com/grame-cncm/faust/blob/master-dev/compiler/generator/jsfx/jsfx_instructions.hh#L349

You can possibly ask again on https://forum.cockos.com ?

Seems not supported: https://www.cockos.com/reaper/sdk/js/basiccode.php#js_basicfunc, so @kartun83 you'll have to do a feature request on Cockos side.
