IEEE numbers support in "string"

[drasmart]

fiftyoneDegreesStringFormat should be extended with

Double = 4,
Int = 5,
Float = 6

Steps:

• Add new IEEE based types, similar to float.h/float.c, with tests
  • fiftyoneDegreesInt
  • fiftyoneDegreesDouble -- wiki^
• Update fiftyoneDegreesString handlers
  • StringBuilderAddStringValue
  • compareValueByName

IEEE double type implementation (with tests):

• https://github.com/postindustria-tech/common-cxx/tree/feature/ieee-double
• (not used yet)

@drasmart and @ben51degrees to verify that they both understand the agreed and final meta data and the data file that includes this metadata in a form that can be consumed by the C code.

@drasmart modify the work to only include the data types that are needed for the agreed and final meta data. We don't want to develop things that are not needed.

This task needs to remove any data types that are not needed but that might have already been implemented.

Used types according to common-metadata:

grep '"StoredValueType": "\w\+"' -r -h -o | sort -u`

"StoredValueType": "IP"
"StoredValueType": "String"
"StoredValueType": "int"
"StoredValueType": "single"
"StoredValueType": "string"
"StoredValueType": "wkb"

So we need the support for only float and int it looks like
