Test discovery fails with very large number of test cases

Checklist

• The issue is about this extension and NOT about a fork.
• Check the known issues list.
• The latest version of the extension was used.
• It is not related to remote-vscode or I checked the following issue

I have a GTest executable with very large number (~150000) tests (actually most of them are different parameter combinations for a single parameterized test). Test explorer just shows the rotating "reload tests" arrow but nothing happens. If I build the test executable without this particular test, it works just find.

To Reproduce

Create a test exectauble with a test with 150000 parameterized variants
Try to use it in VScode

Log (optional but recommended)

The log file ends with this line (I can provide full log via email if needed)
[2020-10-07 13:52:57.292] [INFO] Couldn't parse output file. Possibly it is an older version of Google Test framework. It is trying to parse the output

Hello,

Please fill the Catch2 / Google Test / DOCTest Version: information.

I need more information..

Please run you executable with --gtest_list_tests --gtest_output=xml:tests.xml > stdout.txt 2>stderr.txt and send me the generated 2 or 3 files.

we are using gtest 1.7.
I sent the stdout.txt tou you via email (stderr.txt was empty and tests.xml was not produced)

[matepek]

I haven't received any emails. 🤷‍♂️
Try sending it on gitter as PM.

Hello,

I test it. It actually works just takes a lot of time to parse it.

Hey,
Any news on this? I did some small optimisation. I would like to hear your feedback.
