[dependabot]

Bumps svgo from 2.2.2 to 2.3.0.

Release notes

Sourced from svgo's releases.

v2.3.0

Hey, everybody! We have a big release here.

• The new plugin is added for merging style elements into one. See #1381

Before:

<svg>
  <style media="print">
    .st0{ fill:red; padding-top: 1em; padding-right: 1em; padding-bottom: 1em; padding-left: 1em; }
  </style>
  <style>
    .test { background: red; }
  </style>
</svg>

After:

<svg>
  <style>
    @media print{
      .st0{ fill:red; padding-top: 1em; padding-right: 1em; padding-bottom: 1em; padding-left: 1em; }
    }
    .test { background: red; }
  </style>
</svg>

• CLI got new --exclude flag which uses regexps to exclude some files from --folder. See #1409

svgo --folder=svgs --exclude "invalid-icon" "bad-.+"

• Internal AST is migrated to XAST. This spec makes maintaining plugins easier and may be used as interop with other tools like SVGR.

• The new visitor plugin type combines features of "full", "perItem" and "perItemReverse" plugins without loosing simplicity. Eventually only visitor api will be supported. See #1454

Also small fixes

• override default floatPrecision in plugins with globally specified one (svg/svgo@7389bcd)
• fix rendering -0 in path data (svg/svgo@3d4adb6)
• make browser bundle 30% smaller (svg/svgo@2799622)
• simplified convertPathData plugin (svg/svgo@a04b27a and svg/svgo@6165743)
• prepared for more regression tests (svg/svgo@d89d36e)
