Memory issue between ~4.1 and ^4.2 #288

Hi, since version 4.2, the memory used by swagger-ui-express has been multiplied by 3.

An empty nestJS 8 project which only have typeorm uses ~100MB. With swagger-ui-express@~4.1, it uses ~112MB With swagger-ui-express@~4.2 (and up), it uses ~139MB

(on this picture, main uses ~4.1.6, nestjs-8 uses ~4.3.0)

to reproduce, just swap between versions 4.1 and 4.3

after some investigations, it looks like it comes from the latest version of swagger-ui-dist latest version
