0.4.0: improved completion suggestions

The completions provided by jq-repl were not always usable.

Example, for an object like this:

{
    "a": {
        "hello": "there",
        "AABB": "CC",
        "abc123ZZZ": "cool",
        "5day": "next",
        "abc-123": "test",
        "aaa/bbb": "whatever"
    }
}

We used to generate completions like this:

.
.a
.a.5day
.a.AABB
.a.aaa/bbb
.a.abc-123
.a.abc123ZZZ
.a.hello

Note, that things like .a.aaa/bbb and .a.abc-123 are invalid jq expressions.

With this release the produced completion output is now improved to recognize these issues and produce a more sophisticated completion output, like this:

.
.a
.a.AABB
.a["5day"]
.a["aaa/bbb"]
.a["abc-123"]
.a.abc123ZZZ
.a.hello
