Endlessly query for all transactions bypassing 10k transactions window capped from upstream API

[haxpor]

Such window capped of 10k transactions for one request could be possibly bypassed by setting latest startblock parameter to be endblock parameter of the previous exceeding cap window to the current iteration. Then repeat the process.

For reference, if we exceed the window cap, we will receive the following JSON string

{"status":"0","message":"Result window is too large, PageNo x Offset size must be less than or equal to 10000","result":null}

This would help solved the problem (for example) of https://github.com/haxpor/inoutflow-bsc to be able to analyze for target address with more than 10k transactions. Of course, with this we won't have to worry about the cap again.
