Include the use of ylabs(#) in the help file & enable the option xlabs(#)

[ericmelse]

Dear Asjad,

I am exploring your joyplot / ridgeline to inspect the distribution of categories (y-axis) along a certain range of values (i.e. an index).

It is possible to use the twoway option ylabs(#) to control the size of the y-axis labels, which I appreciate very much.
Although possibly trivial, this option is not documented in the help file.
So, I suggest to include the use of ylabs(#) in the help file.

Not so trivial is that the option xlabs(#) is now not available in joyplot / ridgeline
I would appreciate it also when you enable the use of the option xlabs(#) to control the size of the x-axis labels.

Dear Eric, suggestions noted.
This is one of the first packages I put out there and it badly needs an overhaul. I will keep the points in mind during for the next update.
