Parse raw JSON

Sometimes you need to parse requests which have raw JSON in the body. ambiorix::parse_multipart() only works for ‘form-data’. That’s where webutils::parse_http() comes in.

This is a simple example revolving around how you can select columns and filter rows in the iris dataset when the request body is something like this:

{
    "cols": ["Sepal.Length", "Petal.Width", "Species"],
    "species": ["virginica", "setosa"]
}

Run API

cd into the 13_parse_raw_json/ dir:
```
cd 13_parse_raw_json/
```
Fire up R and restore package dependencies:
```
renv::restore()
```
server.R is the entry point. Run this command in the terminal to start the API:
```
Rscript server.R
```
