gson.fromJson(json, Object.class) and gson.fromJson(json, Number.class)by default parse any numeric input as a Double even when the input is actually an integer. This PR uses the setObjectToNumber() and setNumberToNumber() functions to change the parsing strategy to LONG_OR_DOUBLE so that (small enough) integers are read as Long and only true floating-point numbers (or very large integers) are read as Double. This feels like a more reasonable default for two reasons:
Using Long whenever possible is more accurate.
Floating-point numbers suggest that rounding is acceptable when really it may not be.
