Add check useDictionaryLBR before replace word boundary marker

Add Flag useDictionaryLBR check before replace word boundary marker with U+200B

Hello

I want to fix for some Thai font like TH Sarabun New (Standard Fonts for Thai Public Sectors) because it does not support with ZWSP (U+200B).

The reason that I have to use OTL because some characters require processing before display.
without useOTL and "useDictionaryLBR" => false

with "useOTL" => 0xFF and "useDictionaryLBR" => false

When I add flag "useDictionaryLBR" => false and edit Otl.php:351 for check before process $this->seaLineBreaking(); can fix this issue. See output like this picture below

Added a pull request as I think this edit might be helpful for other Thai people. and this a pull request can fix for issue #1272

Info

This line is have flag useDictionaryLBR before insert U+200B
In Otl.php: 982

But this line isn't have flag useDictionaryLBR before insert U+200B
In Otl.php: 351

I want to add flag useDictionaryLBR check before insert U+200B. This can fix some thai font like Sarabun it does not support ZWSP (U+200B)

There is no reasoning for this, no tests with example code this should fix, no explanation. Can reopen when all this is added.
