Expose functionality to process existing coverage files without running tests.

[jakobjpeters]

I use TestReports.jl to run my tests, which generate the coverage files. I still want to be able to use features in this package though. I'm using this:

using LocalCoverage: generate_xml, process_coverage, report_coverage_and_exit

const package_coverage = process_coverage(; folder_list = [joinpath(dirname(@__DIR__), "src")])

generate_xml(package_coverage, joinpath(dirname(@__DIR__), "coverage.xml"))
report_coverage_and_exit(package_coverage)

However, process_coverage isn't exported. It would be great to access this, and potentially other, functionality without depending on internals.

I tagged a new release with the fix.
