Added MetadataReadAccess/MetadataWriteAccess interfaces and implemented the MetadataReadAccess in VolumeDataLayout.

Fixed name of VDS chunk metadata key since it was changed not to have hyphens (kebab-case) because it is not valid for Azure BLOB storage metadata keys.

Fixed IsChannelAvailable/GetChannelIndex so they do string compare instead of comparing pointers to strings.

Only implemented  requestVolumeSubset

Creating metadata for survey coordinate system and original SEG-Y headers. Changed vector class to have X/Y/Z/T members and proper constructors. Added GlobalMetadataCommon.h and used definitions from there to get correct names. Fixed some previously incorrect names. Replaced to_hexstring() with fmt::format().

and move OpenVDS::Range and OpenVDS::Vector files into the OpenVDS
public header folder

and don't upload constant chunk data

Keep a separate list for dirty pages in the MetadataManager so they don't count toward the page limit and don't get evicted without getting written back.

Set timeouts in AWS client configuration as it appears that it doesn't work with the defaults (https://stackoverflow.com/questions/38647444/aws-c-s3-sdk-putobjectrequest-unable-to-connect-to-endpoint).

Changed VolumeDataAccessManager so it uses the completion callback to take requests out of the pending requests and started putting things in place so the metadatapage can be updated when the request completes. Changed some places to use fmt::format and removed the getDimensionsGroupString() method since we were only using it to build a string that was identical to the one you get from getDimensionGroupName().

Moved download handled/completed callback from run() to constructor since it's supposed to be immutable and fixed that it is actually copied to the member variable. Make sure we initialize m_data in the IOStream constructor so we keep a reference to the data as long as the IOStream exists.
