Extra levels within custom URI scheme

[bbrk24]

Description
source-map-explorer splits up consecutive slashes in custom URI schemes. For example, a folder webpack://src/ is divided into webpack:, `` (empty string), and src.

Steps to reproduce
After building a CRA project with custom CSS, run source-map-explorer 'build/static/css/*.css'.

Files to reproduce
The relevant part is this section from the .css.map file:

"sources":["main.a44e33ca.chunk.css","webpack://src/components/Header/Header.css","webpack://src/index.css"]

Expected behavior
The URI scheme is either removed entirely or left intact.

Environment

• OS: Windows 10
• source-map-explorer Version 2.5.2

Additional context
However CRA does their source mapping, this only happens for CSS, not JS.

It seems like #137 may be a misinterpretation of this issue.
