61bdb49bc7 parser: implement {% raw %} without skip_till 
The implementation is longer than before, but also more correct:
Before, the input `{% raw %}{% endraw }}{% endraw %}` would be a syntax
error, now it renders the string `{% endraw }}`.

b6acf7b3a8 parser: simplify {# comment #} parsing 
`winnow`'s `take_until` with feature `simd` enabled is implemented like
our "optimized" `skip_till`. There is no need to reinvent the wheel.

inclusively.

ca50787f92 parser: macro calls need proper tokens 
With this PR invalid tokens inside a macro call `macro_name!(..)` are
rejected. Otherwise we might emit invalid code that cannot be parsed by
rust.

75dd2c92f3 Update dependencies 
* Update version-incompatible dependencies in examples.
* Update version-incompatible dev-dependencies.
* Replaced deprecated `criterion::black_box`.
* Add `features = "simd"` to `winnow`. This adds a transitive
  dependency to `memchr`, on which we already depend on directly.

3775f4e3a3 Use unicode-ident to determine what is an identifier 
Resolves <https://github.com/askama-rs/askama/issues/442>.

The performance is actually slightly better than before. `unicode-ident`
is highly optimized and jump free.

One test from a fuzzer outcome had to be deleted, because it contained
identifiers that weren't actually identifiers. There is still a test
that tests the same problem, but every identifier is simply `x`. In
another fuzzed test a character [`U+E0049`] was removed.

c1366e0fd8 Re-add {% set %} as alias for {% let %} 
Commit [615fb82] introduced a regression. `{% set %}` and `{% let %}`
should be interchangeable, but only the latter syntax works.

This PR fixes the problem, and adds a regression test.
