We only use that buffer for parsing integer and floats, these
are unlikely to be very big, and if so we can just use RB_ALLOCV as it will
almost always end in a small `alloca`.
This allow to no longer need `rb_protect` around the parser.

And get rid of the Ragel parser.
This is 7% faster on activitypub, 15% after on twitter and 11% faster
on citm_catalog.
There might be some more optimization opportunities, I did a quick
optimization pass to fix a regression in string parsing, but other
than that I haven't dug much in performance.

Ref: https://github.com/ruby/json/pull/718
The existing `Parser` interface is pretty bad, as it forces to
instantiate a new instance for each document.
Instead it's preferable to only take the config and do all the
initialization needed, and then keep the parsing state on the
stack on in ephemeral memory.
This refactor makes the `JSON::Coder` pull request much easier to
implement in a performant way.

Introduce a simplified table for the most common case, which is
`script_safe: false, ascii_only: false`.
On the `script_safe` table, now only `0xE2` does a multi-byte check.
Merge back `convert_ASCII_to_JSON`, as it no longer help much with
the simplified escape table.

Unfortunately Ruby doesn't provide an API to write into

Before this commit, we would try to scan for a float, then if that
failed, scan for an integer. But floats and integers have many bytes in
common, so we would end up scanning the same bytes multiple times.
This patch combines integer and float scanning machines so that we only
have to scan bytes once. If the machine finds "float parts", then it
executes the "isFloat" transition in the machine, which sets a boolean
letting us know that the parser found a float.
If we didn't find a float, but we did match, then we know it's an int.

`rb_cstr2inum` isn't very fast because it handles tons of
different scenarios, and also require a NULL terminated string
which forces us to copy the number into a secondary buffer.
But since the parser already computed the length, we can much more
cheaply do this with a very simple function as long as the number
is small enough to fit into a native type (`long long`).
If the number is too long, we can fallback to the `rb_cstr2inum`
slowpath.

The behavior on such case it quite unclear, the goal here is to
figure out whatever was the behavior on Cext version of `json 2.7.0`
and get all implementations to converge.
We can then decide to make them all behave differently if we so wish.

This is somewhat dead code as unless you are using `JSON::Parser.new`
direcltly we never allocate `JSON::Ext::Parser` anymore.
But still, we should mark all its reference in case some code out there
uses that.

Rather than to copy into a buffer to unescape and then copy that
buffer into the final string, we can directly copy into the final
string.
The downside is that if the string contains a lot of escaping, we
end up returning a string that's larger than strictly necessary, but
it's probably fine.
