Reinstate test for lsimh01.rtf with new data

[shajoezhu]

I see. I am going to merge this in.

tests/testthat/test-lsimh01.R

expect_snapshot_file(write_test_rtf_for("lsimh01.R"), "lsimh01.rtf")

is causing me a bit headache at the moment. Can I leave this with you and fixing in your new version? I think this is related to your data. Thanks. I will create an issue and tag you in. @munoztd0
