Payload definitions are contained in a series of dictionaries.
Repeating and conditional elements are defined as a tuple of
(element size/presence designator, element dictionary). The element
size/presence designator can take one of the following forms:

*Repeating elements:*
 - an integer representing the fixed size of the repeating element N.
 - a string representing the name of a preceding attribute containing
   the size of the repeating element N e.g.

.. code-block:: python

    "groupsat": (
        "IDF010",
        {
            "IDF011": "GNSS Satellite ID",
            etc ...
        },
    ),

*Conditional elements:*
 - a tuple containing a string and a value, representing the name of a
   preceding attribute and the value it must take in order for the
   optional element to be present e.g.

.. code-block:: python

    "optL1CA": (
        ("DF422_1", 1),  # if DF422_1 = 1
        {
            "DF423": "GLONASS L1 C/A Code-Phase Bias",
        },
    ),

A '+1' or '+2' suffix indicates that the attribute name must be suffixed
with the specified number of nested element indices e.g. '"IDF023+1"' -> '"IDF023_01"'

In some instances, the size of the repeating element is derived from multiple
attributes. In these cases the element size is denoted by a composite attribute
name which is calculated within `rtcmmessage.py` e.g. 'NHARMCOEFFC'
