feat: support of record references in toplevel records

[M3lkior]

Description

• the avro parser now support record references as described in Manage reference to object declared previously in avro schema #148
• the avro parser define the x-parser-schema-id attribute with the record name in order to display it in the generated source

Given the following avro record:

{
   "type":"record",
   "name":"RecordWithReferences",
   "namespace":"com.example",
   "fields":[
      {
         "name":"Record1",
         "type":{
            "type":"record",
            "name":"Record1",
            "doc":"Reused in other fields",
            "fields":[
               {
                  "name":"string",
                  "type":"string",
                  "doc":"field in Record1"
               }
            ]
         }
      },
      {
         "name":"FieldThatDefineRecordInUnion",
         "type":[
            "null",
            {
               "type":"record",
               "name":"RecordDefinedInUnion",
               "namespace":"com.example.model",
               "doc":"",
               "fields":[
                  {
                     "name":"number",
                     "type":"long",
                     "doc":"field in RecordDefinedInUnion",
                     "minimum": 0,
                     "maximum": 2
                  }
               ]
            }
         ],
         "default":null
      },
      {
         "name":"FieldThatReuseRecordDefinedInUnion",
         "type":[
            "null",
            "com.example.model.RecordDefinedInUnion"
         ],
         "default":null
      },
      {
         "name":"FieldThatReuseRecord1",
         "type":[
            "null",
            "Record1"
         ],
         "default":null
      },
      {
        "name": "simpleField",
        "type": "string"
      }
