After facebook#9357 we began seeing the following error attempting to acquire locks for file ingestion: ``` FATAL: ThreadSanitizer CHECK failed: /home/engshare/third-party2/llvm-fb/12/src/llvm/compiler-rt/lib/sanitizer_common/sanitizer_deadlock_detector.h:67 "((n_all_locks_)) < (((sizeof(all_locks_with_contexts_)/sizeof((all_locks_with_contexts_)[0]))))" (0x40, 0x40) ``` The command was using default values for `ingest_external_file_width` (1000) and `log2_keys_per_lock` (2). The expected number of locks needed to update those keys is (1000 / 2^2) = 250, which is above the 0x40 (64) limit. This PR reduces the default value of `ingest_external_file_width` to 100 so the expected number of locks is 25, which is within the limit.
