Add support for interpolated strings ("interstrings") (#369)
* Update grammar to support interpolated strings

* Struct initializers, case switchs are regular strings

* Initial stub for interpolated string in AST
This splits the previous STRING_LITERAL terminal into a production,
stringLiteral, to handle REGULAR_STRING terminal and interpolatedString
production.

* Change interpolated strings to expressions

* Fix mode handling in grammar

* Grammar fixes
- Fix mode handling in lexer
- Interpolated strings only have one expression

* Can successfully parse, stub compile interstrings
$"He {there + print("hello")}";

* Add formatting string to grammar

* Fix tests, and add test stubs

* Rename curleys to brace; better AST generation

* initial work interstring instruction

* Initial work on formatted string instruction: emit

* Formatted string instruction: execution

* Add simple formatted string test

* Add formatted string test src

* Review changes #1
- Rename `FormattedString` to `FormatExpression`
- Rename overloaded `try_to_format()` to `get_formatted()`

* Review changes part 2
- Rename `InterpolatedString` ast node to `InterpolateString`

* Review changes part 3
- Modify `ins_interpolate_string`

* Review changes part 4
- Remove unused formal parameter

* Add negative tests

* Spruce up positive tests

* Fix braces, escape chars inside interstring

* Fix, add tests for escaped char and double brace

* Address differences for new lines in tests

* Update Escript version

* Make empty expression an error

* Add documentation for interpolated strings

* Quick touchup on docs
