Faster JSON parsing

[m-muecke]

Since the yyjsonr package is on CRAN now, I wanted to check the openess of having another option for parsing the JSON in req_body_json() with yyjsonr, since it seems to be quite a bit faster.

Quick benchmark:

str <- yyjsonr::write_json_str(iris)
bench::mark(
  jsonlite::fromJSON(str),
  yyjsonr::read_json_str(str)
)
#> # A tibble: 2 × 6
#>   expression                       min   median `itr/sec` mem_alloc `gc/sec`
#>   <bch:expr>                  <bch:tm> <bch:tm>     <dbl> <bch:byt>    <dbl>
#> 1 jsonlite::fromJSON(str)      284.5µs  298.6µs     3298.    1.29MB    16.5 
#> 2 yyjsonr::read_json_str(str)   26.9µs   27.9µs    34519.    9.69KB     3.45
