Memory leak when inserting binary values

[aistis-]

Hello, after fixing inserting binary values via put method, I've tried to use it in a long-running process. I observe a memory leak and it seems PHP garbage collector is not able to clean Value::blob(...) objects.

I'll try to put some steps to reproduce the issue, but reporting the issue in advance as someone may already have an idea what could be wrong. I cannot yet confirm is it for all the value objects or only the blobs.

FYI @paul-brackin

I was able to reproduce the memory leak. Added an example to this PR: #67

Works fine when inserting a regular string or Value::string(...).

Should be resolved in the latest main branch.
