User-defined ISO8583 formats support

[timgabets]

As we all know, there are tons of different flavours of ISO8583, but currently the format specification is harcoded in formats.js

I think it would be generally a good idea to implement a user-defined ISO8583 customizations support in the library. Probably, from the user's point of view it may look like this:

// Create the new ISO8583 format, which will be exact the same 
// as the default one from lib/formats.js, 
// but with the different DE12 (n6 type changed to n12):
let format = {
  12: {
        ContentType: "n",
        Label: "Time, local transaction (hhmmss)",
        LenType: "fixed",
        MaxLen: 12
    },
}
let isopack = new iso8583(data, format);

I think this will make the library more flexible and customizable.

Any thoughts/ideas are welcome ;)

If you are okay with that, I'll start the development soon.

Are you guys working on this idea? Is this available on a branch or on a repository I can take a look at?

[zemuldo]

@zemuldo Hi I think the issue is still there following is my code. I think it is specific to Bitmap. When I try to change ContentType from 'b' to 'an' it does not effect.

let customFormats = {
    '1': {
        ContentType: 'an',
        Label: 'Bitmap',
        LenType: 'fixed',
        MaxLen: 8
    }
};
const isopack = new iso8583(data, customFormats);
