feat: do not read size of blocks for want-have requests

[gammazero]

When the replace-have-with-want-blocks is disabled, the block sizes for blocks corresponding to have-want requests are not read and instead the blockstore is checked only to see if the block is present.

The replace-have-with-want-blocks feature can be disabled using the new WithReplaceHasWithBlockMaxSize(n) option which can be used with bitswap.New. It sets the maximum size of a block in bytes up to which we will replace a want-have with a want-block. Setting a size of 0 disables want-have replacement and means that block sizes are not read for want-have requests.

This is a prototype fix for issue #657
