Add missing scanBlankSpace parsing &&s
Add `lex.scanBlankSpace()` to the loop in `Parser.parseLogicalAndExpr` so that multiple consecutive `&&` comparison expressions delimited by blank spaces will be properly parsed. Add tests to ensure that the multiple consecutive `||` comparison expressions are also properly parsed. Thanks @jarangutan for the report and @jg-rp for the analysis. Resolves #24.

### 🐞 Bug Fixes
2020

2121
* Allow `true`, `false`, and `null` to be used as selectors, e.g., `$.true`.
22+
* Fixed bug that prevented multiple blank-space delimited ANDed comparison
23+
operations from being parsed. For example, `$[@.x=="hi"&&@.y!=3&&@[1]==1]`
24+
would parse but `$[@.x == "hi" && @.y !=3 && @[1]==1]` would not. Thanks
25+
to @jarangutan for the bug report and @jg-rp for the analysis ([#24]).
