Function handler parameter mapping splitting inputs which include colon character

[mshangle1]

Describe the bug
When providing parameters to function mapping (ie: $F{sum:1,2}), if the parameter includes a : character, the rest of the parameter is cut off from being included in the arguments.

I am trying to create a function which will allow to give some ISO DateTime format to the method and generate a DateTime with the given format.

To Reproduce
Steps to reproduce the behavior:
Example: $F{CurrentDate:yyyy-MM-dd'T'HH:mm:ss}

Function:
function currentDate(ctx){ some code here }

Adding Function Handler:
handler.addDataFuncHandler('CurrentDate', (ctx) => {return currentDate(ctx)})

When reaching the function, the only value included in ctx.args[0] is yyyy-MM-dd'T'HH which is cutting off the mm and ss parts of the ISO format.

Expected behavior
The expected behavior in my case would be to allow the function args/parameters to include the : character and not be split when processing the input.

Potential Solution
In dataProcessor.js line 104, the FunctionName:param1,param2 string is being split up by the : character for all instances of the character, causing arguments which include a : to be split and not passed to the function when it is filtered out on line 106.

I was able to reach expected behavior by modifying the refValue.split(':') on line 104 to use a regex expression to only split by the first instance of the : character like so refValue.split(/:(.*)/)

If there is already some way to allow arguments to include the : character without any changes please let me know. Otherwise I think a change would be required to allow it.
