Add ignore_extensions option for vectorial files

[berarma]

When using SVG files the plugin is very slow processing them and it would be best to use the original SVG file anyways.

I could avoid using this plugin for vectorial images but then migrating from bitmap to vectorial involves changing template logic making it harder. Also, images get mixed and it may be hard to notice when rescaling is being done in the wrong files.

I think it's easier to have the plugin be able to bypass processing vectorial images and just invoke the template with the original file path.

Thanks for your time.

PD: I'm new to Ruby, these are almost my first lines of code besides some basic Jekyll plugin.

Hey, thanks for your PR! My gut feel is that this logic would be better in your templates. Is there a reason this wouldn't work?

{% assign path = 'assets/vector.svg' %}
{% assign extension = path | slice: -3, 3 %}

{% if extension != 'svg' %}
  {% responsive_image_block %}
    path: {{ path }}
  {% endresponsive_image_block %}
{% else %}
  <img src="{{ path }}">
{% endif %}

It would work but having to repeat this code for every image isn't ideal. I will write a custom plugin to do it, or maybe an include file.

I just thought it could be useful for more users and wanted to give it a try.

I'll try now writing a custom plugin. It should be as easy.

I would also find this very useful :)
