lang/fennel: update to fennel-1.5.1

== 1.5.1 / 2024-08-24

--- Bug Fixes

* `,doc`/`fennel.doc`: Don't mutate `:fnl/arglist` directly when
  showing callable form
* `(set (. tgt k1 ...) v)` now works on known globals and
  `$, $1 ... $9` in hashfns
* Macro quote expansion no longer breaks when `sym`, `list` or
  `sequence` is shadowed
* Bring `fennel.traceback` behavior closer to Lua's `traceback` by
  not modifying non-string and non-`nil` values.
* Avoid losing precision when compiling large numbers on LuaJIT.
* Add syntax for representing infinity and NaN values.

== 1.5.0 / 2024-06-23

--- New Features

* Macro `pick-values` is now a special, allowing it to emit better
  Lua output.
* Add `fennel.getinfo` as source-map-aware equivalent of
  `debug.getinfo`.
* Optimize allocation away when destructuring tables to tables.
* Allow `&` and `&as` in the same destructure clause.
* More consistent module-not-found warnings for `--require-as-include`.
* Improve compiler output for `and`/`or` forms with potential
  side-effects.
* Allow locals in places where they make sense rather than
  mid-expression.
* Accept `--keywords` option to add to the list of built-in
  Lua keywords.
* REPL completion now works on partial REPL commands:
  e.g. `,complete ,d` -> `,doc`.
* Tables in the REPL default to printing with limited depth.
* View settings in REPL can be changed:
  `(set ___repl___.view-opts.depth 100)`.
* Support dynamic field names in `(set (. tbl field) val)`.
* The `fennel.compile` function now accepts an AST, iterator, or file.
* Catch typos when a space is missing after a string.

--- Bug Fixes

* `(pick-values 0 (side-effects))` now correctly preserves side
  effects
* Don't non-nil assert on `_foo` arguments in `lambda`.
* Propagate compile options into `,compile` repl command.
* IIFEs emitted by `and`/`or` inside `(fn [...])` now propagate
  varargs.
* `macrodebug` on cyclic macro expansions now serialize to valid code
  (no `@1, ..`)
