Large CRL on live example causes browser to hang #290

I downloaded a CRL from http://crl3.digicert.com/ssca-sha2-g6.crl and tried to load it on the live example page https://pkijs.org/examples/X509_cert_complex_example.html into the "Load CRLs (binary):"

The CRL is 17MB in size. My browser tab became unresponsive for 1 minute. 1 core of CPU went to 100% percent and around 2,5 GB of memory was used up.

@themighty1

sample was created with focus of showing how to use pki.js
the sample currently parses in a blocking location of the code
to fix that will require moving it to a separate thread

We could try to enhance the example in a future but no estimates right now.
