ImportOrderingRule breaks when ij_kotlin_imports_layout entry has spaces after commas

[Kernald]

Expected Behavior

Spaces in .editorconfig's ij_kotlin_imports_layout should not matter. E.g. this:

ij_kotlin_imports_layout = *,^

Should behave in the exact same way as this:

ij_kotlin_imports_layout = *, ^

Observed Behavior

ktlint seems to stop parsing the line at the first whitespace. With ij_kotlin_imports_layout = *, ^, I get the same results as ij_kotlin_imports_layout = *. Note that IntelliJ properly supports whitespaces.

Steps to Reproduce

1. Set this in your .editorconfig, and reformat it:

[.editorconfig]
ij_editorconfig_space_after_comma = true

[{*.kt, *.kts}]
ij_kotlin_imports_layout = *,^

2. Run ktlint -F on a file with an import alias. Notice the ordering is now incorrect.

Your Environment

• Version of ktlint used: Tested in both 0.41.0 and 0.42.1
• Name and version (or code for custom task) of integration used (Gradle plugin, Maven plugin, command line, custom Gradle task): CLI
• Version of Gradle used (if applicable): n/a
• Operating System and version: macOS 11.5.2
• Link to your project (if it's a public repository): n/a

In the readme a similar problem is documented: https://github.com/pinterest/ktlint#intellij-idea-editorconfig-autoformat-issue which was documented as a result of #762. Both that problem as well as this issue can be prevented by advising to disable this setting and reformat all '.editorconfig' files in the project.

[.editorconfig]
ij_editorconfig_space_after_comma = false # Workaround for parsing problem of .editorconfig by KtLint

Woops, sorry I didn't see the readme entry nor the existing issue. Sorry for the noise.
