add LSQB queries as test

[aziz-mu]

• Added LSQB queries q1 - q9 as a test. Queries q8, q9 are translated to use WHERE NOT EXISTS {} syntax
  Queries' descriptions can be found at: https://github.com/ldbc/lsqb
• Added the dataset sf-0.1 from https://repository.surfsara.nl/datasets/cwi/lsqb . This is the smallest dataset to run the LSQB queries (~50MB).

Expected output from tests sourced from https://github.com/ldbc/lsqb/blob/main/expected-output/expected-output.csv. All tests pass.
