[health 3.4.4] missing HealthDataTypes in the json helper const HealthDataTypeJsonValue

[fix92]

(will open a PR shortly for this)

Describe the bug

When calling toJson() on fetched HealthDataPoints that are being read from health, a const Map<HealthDataType, String> HealthDataTypeJsonValue is used to determine the string value in the json, usually just the lower case enum name.

In November 2021 five nutrition data types were added where those values have not been added to this Mapping: #430

  DIETARY_CARBS_CONSUMED,
  DIETARY_ENERGY_CONSUMED,
  DIETARY_FATS_CONSUMED,
  DIETARY_PROTEIN_CONSUMED,
  FORCED_EXPIRATORY_VOLUME,

To Reproduce

Read any of the above described data types from health and call toJson() on them.

Expected behavior

A Json Object containing a non-empty String in the data_type field.

Actual behavior

A Json Object containing an empty String as data_type field.

closing this as the HealthDataTypeJsonValue was replaced to a proper generic way of serializing to json
