Add stylistic alternate for 19th century F clef

[MrFuzzywump]

There are two symbols that I cannot find in SMuFL, those are what (I think) are called “Before 1840 C and F clefs”, before 1840 versions of C and F clefs.

The C clef appearance is already included in SMuFL (it's U+E060, cClefSquare in the Clefs category).

But the F clef appearance is not currently included, so that's something we could add in future.

I found another example of the "Before 1840 C and F clefs" (1835):

They're everywhere. The question is whether this is a separate glyph or a different font? Because just about everything looks different in 19th century publications.

This is the bass clef from before 1840 (year < 1840). This is a stylistic alternate. Just like the "Before 1840 C clef" I mentioned earlier.
I also found another score that has the "Before 1840 C and F clefs" (1791):

I based mine on the common time symbol:

What would you base the "Before 1840 F clef" on?

[MrFuzzywump]

The "Before 1840 F clef" was used before 1840, hence the name, and in the 18th century.

[MrFuzzywump]

I have disagreement on whether it's 18th century or 19th century

[MrFuzzywump]

We have disagreement on whether it's 18th century or 19th century

[MrFuzzywump]

I would call it simply earlyModernFClef since we have disagreement on whether it's 18th century or 19th century and that term mostly covers either.
