adjust column size to accommodate uppercase letters

[florian08fr]

hello.
thanks for your class, it's really useful.
when a cell contains text in uppercase only, a column width adjustment could be done line 831:

simplexlsxgen/src/SimpleXLSXGen.php

Line 831 in a44de02

$vl = mb_strlen($v);

by adding something like:
$vl+=intval(0.2*mb_strlen(preg_replace('![^A-Z]+!', '', $v)));

Also, it could be very useful to have a parameter that deactivates the limitation of the column width to the value 60 in line 961, or alternatively that the value 60 be customizable in the default variables, without having to define a fixed column width in our php script:

simplexlsxgen/src/SimpleXLSXGen.php

Line 961 in a44de02

$w = isset($this->sheets[$idx]['colwidth'][$k]) ? $this->sheets[$idx]['colwidth'][$k] : min($max + 1, 60);

best regards.

just use setColWidth

simplexlsxgen/src/SimpleXLSXGen.php

Line 1100 in a44de02

public function setColWidth($col, $width)
