support for JSON number as variables

[alex-bluetrain]

it's not possible to use json numbers as variable in the template without breaking the json format,

example

{
    "name": "{user.name}",
    "age": {{user.age}}
}

when importing such file you get an Unexpected token { in JSON at ...

I could enclose the age value in doublequotes, but that will make it a string and violates the format I'm supposed to be compliant with. (HL7 FHIR objects)

PRs welcome :)

@alex-bluetrain Do you have any ideas for how to potentially solve this? I agree it would be a nice feature to have.

I've added a failing test case for this here #32
