Update v.2.3.9/v.1.3.9

5 October 2022

New hook 'woocs_precision_on_calc' - needed if prices are very low. For example, paper clips are sold at $0.000423 and the minimum order is from 10,000. In order not to fall exactly during the conversion, it is worth transferring:
```
add_filter('woocs_precision_on_calc', function ($precision, $currency) {
    $precision = 6;
    return $precision;
}, 10, 2);
```
New currency aggregator "National Bank of Moldova"
New currency aggregator "Magyar Nemzeti Bank"
New currency aggregator "Currencyapi.com"
For shortcode - [woocs_show_custom_price value=20 decimals=6 currency=USD] added new attributes:
- decimals - number of decimal places currency
- currency - if specified, then the shortcode will show the price in one currency only, regardless of the current currency
For shortcode [woocs_price id=87 currency=EUR] added new attribute 'currency' -> the price will be indicated in the assigned currency, regardless of the current currency
New hook 'woocs_product_fixed_price_data_simple_types' - passes an array with product type slugs. Specifies which type of products fixed prices can work with. If the user decides to add a custom type, he needs to do a compatibility test with fixed prices. Essentially a hook for developers who know what they are doing
New hook 'woocs_order_formatted_prices' - added price formatting on: "Order page" and "Thank you page" - if you pass false then there will be no formatting there
New attribute 'css_class' for shortcode [woocs css_class="woocs_clean_select"] which allows you to add to tag <select> custom css classes + special value there 'woocs_clean_select' which allows you to avoid applying of selected skins and always show pure drop-down
For premium version added "Currency Wizard" - search and add multiple currencies with all data: flag, rate, sign, description, etc.
