Description
When running commands from the Development section of Readme tests fails with:

test mem::inlineskiplist::tests::test_mem_alloc ... ok
thread '<unnamed>' panicked at library/core/src/panicking.rs:221:5:
unsafe precondition(s) violated: slice::get_unchecked requires that the index is within the slice
thread caused non-unwinding panic. aborting.
error: test failed, to rerun pass `--lib`

Caused by:
  process didn't exit successfully: `/home/etsilence/Documents/wickdb/target/debug/deps/wickdb-6d513c75eecb80d0` (signal: 6, SIGABRT: process abort signal)

Additional context
Not sure if that's my environment issue or tests itself fail.
