if cmake parameters TEST_SEGY_FILE and TEST_URL with optional
TEST_CONNECTION then the test will used said parameters import the SEGY
file with default parameters, and then export the VDS to a local SEGY
file. It will then do a SHA256 hash of both files and validate that the
hashes er the same.

Add overloads allowing create and open to be called only with url. And

remove LRU cache and revert back to a cache similar to the original design, except that we explicitly tell the cache when to drop completed inlines

Added a method to create index entries for chunk data which allocates space in the VDS file and makes it possible to write the data without holding a lock.
