add jsonGetBooleanArray and jsonGetRealArray

[eine]

jsonGetBooleanArray and jsonGetRealArray are added, with the same implementation approach as jsonGetIntegerArray: see #7.

However, there is an issue with the current implementation: boolean'value and real'value are used. As explained in #7 (comment), this is not supported by Vivado. Therefore, to_boolean(str : STRING) return BOOLEAN and to_real(str : STRING) return REAL need to be written. to_natural_dec can be used as a reference.

Furthermore, since time_vector is also defined in VHDL 2008, the same approach can be followed to implement jsonGetTimeArray(JSONContext : T_JSON; Path : string) return time_vector. This would require a to_real(str : STRING) return REAL function, along with jsonIsTime(JSONContext : T_JSON; Path : STRING) return BOOLEAN (which does not exist, yet).

Please remove 2.5, .

Boards0.json was derived from Boards1.json as the maximum possible JSON example, that doesn't cause Vivado to explode. Synthesis time was exponentially growing by each character in the string.

If you need more complex test, please extend other files or create a new input file. I would like to keep this string short and simple until Vivado can handle strings efficiently.

Done. Nonetheless, note that this PR won't work in Vivado as is. See first comment above.

@Paebbels is this still active? A wish for this PR from Trumpf XD. Also wishes for real and integer type

[Paebbels]

@yangyt96 I know, the repository isn't broken and it's actively used e.g. by VUnit. I'm open for contributions and updates. There is also a potential request by OSVVM, if a protected type based variant could be added usable in simulation with better speed and resource usage. (In the synthesizable variant, all data structures are pre-allocated to limit the maximum usage.)

For which tool do you need it?

• I need to check how I can check it on all synthesis tools and synthesis versions

• I need to check how I can check all simulators as well.

[yangyt96]

Currently we don't use it for synthesis, only for simulation. I use intensively with riviera-pro.
