feat: display all valid fields

[Bugs5382]

• A function that will parsing the BSH, MSH, or FHS will parse out the entire tree either as an XML, JSON,, or OBJECT.
• This way a user can see what field they need to get from a particular message when doing their initial interpretation of where certain data is.

message = new Message({
        messageHeader: {
          msh_9_1: 'ADT',
          msh_9_2: 'A01',
          msh_10: randomControlID,
          msh_11_1: "T"
        }
      })

should output:

{
        "MSH": [{
          path: "MSH.1",
          value: "|"
        }, {
          path: "MSH.2",
          vale: "^~\\&"
        }, {
          path: "MSH.9.1",
          value: "ADT"
        }, {
          path: "MSH.9.2",
          value: "A01",
        }, {
          path: "MSH.9.3",
          value: "ADT_A01"
        }, {
          path: "MSH.10",
          value: randomControlID.toString()
        }, {
          path: "MSH.11",
          value: "T"
        }, {
          path: "MSH.12",
          value: "2.7"
        }]
      }

The idea will be:

that you can take a whole message object and do:

const fields = message.displayAll()

... in which fields will then contain in order each segment (in order), and since we know they are the "segment," we can loop through the fields, and only fields that have "info" would be put into the array. In the end, it will create a formatted array, which then can be maintained by the end-user however they want.
