CIP-0008: Update and Refinement to CIP-0002

CIP-0008 proposes to double the amount of free traffic available on DevNet by increasing the "burst amount" within the free traffic window. This adjustment is necessary because the current free traffic allocation, set by CIP-0002, is insufficient for application developers and new validators to complete essential transactions like purchasing additional traffic. The change aims to facilitate development and network participation without entirely eliminating the need for users to manage a traffic balance.
