…c to separate get method (peterjaap)This PR was squashed before being merged into the 5.1-dev branch.Discussion----------[Console] Moved estimated & remaining calculation logic to separate get method| Q             | A| ------------- | ---| Branch?       | master| Bug fix?      | no| New feature?  | yes| Deprecations? | no| Tickets       | -| License       | MITThis way, we can use `getEstimated()`and `getRemaining()` to get easy access to the estimated / remaining number of seconds to be used in our placeholder definition set with `setPlaceholderFormatterDefinition` without having to redefine the calculation ourself.Example before;```phpProgressBar::setPlaceholderFormatterDefinition(    'eta',    function (ProgressBar $progressBar) {        $estimated = round((time() - $progressBar->getStartTime()) / ($progressBar->getProgress() ?: 0.1) * $progressBar->getMaxSteps());        return date('H:i:s', strtotime('+' . $estimated . ' seconds'));    });```Example after;```phpProgressBar::setPlaceholderFormatterDefinition(    'eta',    function (ProgressBar $progressBar) {        return date('H:i:s', strtotime('+' . $this->getEstimated() . ' seconds'));    });```Commits-------19958fb [Console] Moved estimated & remaining calculation logic to separate get method
