Make `>` and `<` valid function/symbol names

[datwaft]

I am using the latest Neovim nightly version.

Symbols using those characters look like this:

Here is the code I used for this test:

(fn str->tbl [str]
  (icollect [chr (string.gmatch str ".")] chr))

(str->tbl "Hello") ; Returns ["H" "e" "l" "l" "o"]

(fn ->str [obj]
  (tostring obj))

(->str 1) ; Returns "1"

For reference, the following is output I get for the tree-sitter cli's parse subcommand using https://github.com/TravonteD/tree-sitter-fennel/commit/bc689e2ef264e2cba499cfdcd16194e8f5fe87d2:
