8011a9cde1 Unit test should not pass with bad key 
Unit test needed to capture a bad key scenario, which did not get returned false.  However, bad keys are now CRC checked and so willalways return false - and so the case clause for bad key can be dropped.

d468dd32a8 More consistency in extract value functions 
Try to make this a little bit cleaner and more obvious.  Make sure the value passed is always a value and not a crc/value.

7cc5512a0a safe_read 
There are now two cases of safe_read_next_key/2

the first case using the original function name will return just the Key when positive (not the Key and KeyBinary).  If the Key and KeyBinary is required (e.g. for CRC checking purposes), then use safe_read_next_keyint/2.

d56ff6efbc Make CRC check cover key and value 
So that a corrupted key is detected through a CRC check without crashing leveled (e.g. because it binary_to_term/1 failes somewhere or it is a tuple of the wrong length).

Previously the CRC covered the value only.

Note if you only wish to extract the value, the key cannot be independently validated.  Perhaps a process extrating key only could hit issues.

18aabb49ba Segment filter and multiple keys in slot 
An issue was spotted.  If we use a segment filter in a query, and there are multiple matches within a given slot - only the first match is returned.

Tests didn't detect this.  Now they do, and the issue is resolved.

5414e18047 Accumulate keys in check_blocks 
Previously couldn't accumulate keys using check-blocks - so if a key was found in the first position, and there were other positions to check for other keys, those other positions wouldn't be checked.

6a20b2ce66 Use leveled_codec types 
... and exporting them.

Previously types wer enot exported, and it appears dialyzer treated tham as any() when they were unexported types ??!!??

941d4d2577 Fix issue with use of ets:next 
ets:next is not StartInclusive - so we shouldn't use ets:next when querying the ledger cache, until it has been confirmed thta a matching key to the StartKey is not present.

This reoslves the intermittently failing unit test which highlighted this (and also makes that intermittent failure a permanent failure by expanding the test cases it covers).

b81caf7dee segment_hash -> tictac 
the concept of the segment hash belongs to the leveled_tictac module, not the codec.

Previously the alignment of tictac and store was accidental, this change makes it explicit.
