Bug in compare_colour() with from_space="hcl"

[jmw86069]

First, I love your R work, your generative artwork, overall it is quite inspiring. Much respect.

I have found a bug. It's simple but important.

In farver.cpp the function compare_dispatch_from() does not include an entry for Hcl. It should be the 13th entry, as with compare_dispatch_to().
As a result, the following example returns the first HCL color, which "should never happen" but unfortunately does:

farver::compare_colour(farver::decode_colour("#BB1133", to="hcl"),
   farver::decode_colour("#AA0011", to="hcl"),
   to_space="hcl",
   from_space="hcl")

Output:

        h   c    l
[1,] 7.93 117 39.9

(Expected output is a numeric distance.)

I have another issue - I will report separately. Thank you!
