Faker.cpp v0.0.8

Manual Faker.cpp release built from 7ea57106c29ff4257e847d34e667330eb12a3692.

Performance

Benchmark workload: 10 runs per OS, 1000000 rows per run, 48 generated values per row. The tables use median results.

Aggregate rows are only directly comparable when the generated-result count is unchanged. Per-result rows show matching generators independently.
