Fix attribute datatypes in TIFF plugin

[MarkRivers]

This PR does 2 things:

• Modifies myAttributeFunctions.cpp to generate attributes of all numeric datatypes. This allows thorough testing of the TIFF plugin and other applications that handle NDAttributes.
• Fixes the TIFF plugin to handle all numeric attribute datatypes correctly. Signed and unsigned integers are handled separately. All integer types are converted to 64-bits before being converted to ASCII.

A new attribute XML file was added to simDetector to generate an instance of each attribute numeric datatype.
https://github.com/areaDetector/ADSimDetector/blob/master/iocs/simDetectorIOC/iocBoot/iocSimDetector/testAttributeDataTypes.xml

I tested ADSimDetector using that XML file.

I printed out the values of the NDArray attributes:

The numeric attributes with names like Int8, UInt8, ... Float64 all have the correct data types and values.

I then saved a TIFF file, and ran tiffinfo on it:

The values of all the numeric attribute datatypes are correct.

[MarkRivers]

I suggest we use this PR rather than #518

[mp49]

Hi Mark, thanks! I can test this today or tomorrow, and I'll post the results here.

[mp49]

I've tested the patch and it seems to work.

Using the unpatched master branch I could reliably reproduce the problem in #519 (although strangely the first TIFF file written after an IOC reboot was always ok), and when I switched to this patched branch the issue was fixed.

I'll delete my pull request
