Memray tests for memory leaks for head() and tail()

[grusev]

Reference Issues/PRs

The test creates has a special fixture to setup needed environment (not in test as it slows extremely execution under memray)

• creates library with predefined by test library options, then adds a symbol and creates many versions and a snapshot for each version. The dataframes created are growing in size when library is dynamic.

The test runs is executed 2 times with different library options for segments size, dynamic type on/off, and encoding version.

It covers head and tails executions with different parameters over different types of versions/snapshots of a symbol

NOTE: utils.py is not part of this PR. It is part of #2185 but is there to reuse code as the other is not yet merged
