More granular options for character variants [ cv10 (i and l alternates ; Neon, Argon, Xenon, Radon) and cv11 (j, f, r and t alternates ; Neon, Argon) ]

[jothefiredragon]

Hi, I wanted there to be more granular options for some character variants:
Currently, two cv's control 6 Latin letters:

• cv10 (l i alternates ; Neon, Argon, Xenon, Radon)
• cv11 (j f r t alternates ; Neon, Argon)
  I want this to be changed so that character variants for each of the letter f, i, j, l, r and t are toggled by different cv's such as:
• cv14 (f alternates)
• cv15 (i alternates)
• cv16 (j alternates)
• cv17 (l alternates)
• cv18 (r alternates)
• cv19 (t alternates)

Thank you very much in advance for your consideration.

P.S. The scope of this issue covers that of this issue: #351
