[IMP] format: implement multi-part format

This commits adds the possibility to have a format with multiple parts, as well as improving/fixing the behaviour of currently implemented formats.

The formats are now tokenized and parsed in a more structured way, which allows for more complex formats to be implemented. Some example of things that are now supported are:

• multi parts format, separated by a semicolon
• multiple escaped strings in a number format
• strings can now be escaped with quotes, and chars with backslash
• escaped string now support [ characters inside of them
• can now have any separator/escaped string inside a date format
• number formats with escaped strings in the middle are now correctly handled (before formatting 123 with format 0[$$]0 would return 123$123 instead of 12$3)
• we support format on strings

[IMP] format: handled more complex text format

Also removed the PLAIN_TEXT_FORMAT variable. The variable made it looks like the @ was an immutable special case, whereas @ is just a text placeholder that can be used in more complex text formats.

[IMP] currency format: add accounting format:

This commits adds the accounting format. This is similar to a currency format, except that negative values are displayed in parentheses and zero is displayed as a dash.

Also changed the model config defaultCurrencyFormat to defaultCurrency, so it can be used for both currency and accounting formats.
