Consider having get*() methods convert value to desired type

[proppy]

We should consider having get*() methods convert the corresponding value to the desired type if possible.

Ex:

• .getInt(): "13" -> 13
• .getString() : 13 -> "13"
• .getFloat(): 13 -> 13.0

What do you think @kotl ?

I support this proposal.
I use an application made with Thunkable that has a Firebase extension that in my case sends everything in String i.g. :
int: 55 ---> "55"
String: text --->""text"" (String of String displayed like this on firebase: "\"text\"")
bool: true --->"true"
float: 5.5 ---> "5.5"

So now i have to use my own function to convert.

I absolutely agree. Classic C++ SDK has support for that through Variant:
https://firebase.google.com/docs/reference/cpp/class/firebase/variant#classfirebase_1_1_variant

it would be nice to use similar naming and appropriate supported types only.
(please use int64 for int types, in esp8266 it is either 'signed long long' or 'sint64', I think)
