0.2.0 #

Breaking: JsonObject no longer implements Map<String, Object?>, so obj['k'] and obj['k'] = v do not compile. To migrate:

0.1.x	0.2.0
`obj['k']`	a typed reader (`obj.string('k')`, ...), or `obj.raw('k')` for a value read with a pattern or passed on
`JsonObject.of({...obj, 'k': v})`	`obj.withFields({'k': v})`
`JsonObject.of({...a, ...b})`	`JsonObject.merge([a, b])`
`JsonObject.of({...obj}..remove('k'))`	`obj.without({'k'})`
`obj.keys`, `obj.entries`	`obj.keys`, with a reader for each value
`obj.containsKey(k)`	`obj.has(k)`
`JsonObject.unmodifiable(obj)`	`obj.frozen()`
`obj` passed to a parameter declared as a `Map`	`obj.asUncheckedMap()`
`jsonEncode(obj)`	unchanged: it writes a `JsonObject` as it is

Add withFields, JsonObject.merge and without, which each make a new object from others, and keys.
Add frozen(), a copy that refuses changes. Shallow: nested objects and lists are shared.
Add asUncheckedMap(), a read-only map view for a parameter declared as a Map.
JsonObject implements Object, so it is never null and an extension on T extends Object applies to it. (Without implements Map, it would otherwise be only an Object?.)

Add JsonObject, an extension type over Map<String, Object?> that can only be made from raw data through a door that checks it (JsonObject.decode, JsonObject.parse), with typed readers (string, integer, number, boolean, object, list, strings, objects, each with an OrNull twin) plus has and raw.
Add JsonFieldException, the FormatException a reader throws naming the field that is absent or the wrong shape, and the shape it wanted.
Add wholeNumber, which reads 3 or 3.0 as an int and refuses fractions and doubles of 2^53 or more in size.
