* [postgres] Add support for custom binary operators
More details about operators in general are at:
https://www.postgresql.org/docs/current/sql-createoperator.html. This
patch attempts to parse `SELECT` queries that reference an operator
using `OPERATOR(<optional_schema>.<operator_name>)` syntax.
This is a PostgreSQL extension. There are no provisions for user-defined operators in the SQL standard.
* fix code-review comments and ci failures
* Allow custom operator in generic dialects too
* Parse `OPERATOR` as Vec<String>
* fix: std

* Redshift square bracket handling
We need to detect `[` or `"` for Redshift quotes around indentifier and at the same time exclude
treating JSON paths as indentifer

* recover original test cases
* fix cargo clippy
* fix: Handle double quotes inside quoted identifiers correctly
This fixes#410 for standard SQL, however I don't know enough about other dialects to know if they
handle this differently. May need more extensive testing as well.
* refactor: Make quoted identifier parsing a seperate function
* test: Check that quoted identifier tokenization works
Added `pretty_assertions` so that the `assert_eq!` in the tokenization is readable
* test: Check that quoted identifiers work in mysql
* chore: cargo clippy

To share helper macros between various tests/* we added a new module
(tests/macros/mod.rs). This made the prologue to be used in tests quite
long and a little weird:
```
#[macro_use]
#[path = "macros/mod.rs"]
mod macros;
use sqlparser::test_utils::*;
```
This simplifies it to:
```
#[macro_use]
mod test_utils;
use test_utils::*;
```
- and switches all existing tests to the new prologue simultaneously...
...while fixing a few other inconsistencies and adding a few comments
about the way `test_utils` work.
The Ident type was previously an alias for a String. Turn it into a full
fledged struct, so that the parser can preserve the distinction between
identifier value and quote style already made by the tokenizer's Word
structure.
