[NFR]: HJSON Config Support

[ghost]

Request for HJSON (https://hjson.github.io/) in phalcon configs it supports comments and allows to write easier to read JSON configs. It can have similar functions to existing Configs in https://docs.phalcon.io/4.0/en/api/phalcon_config

HJson config example:

/* HJson Config Example 
 Created Sep. 29th, 2021 */
[
  # Phalcon Config
  phalcon: [
    // App Base URI
    baseuri: /phalcon/
    # Some Models
    models: [
      metadata: memory
    ]
  ]
]

PHP example based on docs:

use Phalcon\Config\Adapter\HJson;
$config = new HJson("path/config.hjson");
echo $config->phalcon->baseuri;
echo $config->models->metadata;

Valid HJSON File:

{
  # Comment
  // Comment
  human:   Hjson
  /* Comment */
  machine: JSON
  /* RegEx Allowed */
  RegEx: \s+
  # Multi Line Allowed
  md:
    '''
    First line.
    Second line.
      This line is indented by two spaces.
    '''
  // allow trailing commas
  list: [
    1,
    2,
  ]
}

We will let the community decide on this.

My 2 cents though: why is this necessary? I can see the benefit of having such functionality but json_encode and json_decode are the two main methods used when parsing JSON and are part of PHP. To introduce HJSON one has to implement something that would allow the parsing of the file with HJSON format.

I checked GitHub and there is such a parser but it is around 1-2k lines long. To introduce such complexity into Phalcon will make this parsing slower and not faster plus it will be bloat on the framework.

/0.02 USD.

Closing in favor of #14608 (comment) Will revisit if the community votes for it, or in later versions.
