Expedited: Add TIA as Fee Token

This proposal would add TIA as a valid fee token for Osmosis transactions. \n\nThis allows users whose only interaction with the Cosmos ecosystem is via Celestia to be able to transact for the first time on Osmosis. \n\nAs Osmosis is aiming to be the primary market for Celestia and rollups using the TIA token this proposal is considered to be important for the functioning of this market and so is being proposed as an expedited proposal. \n\nFee tokens currently can only be routed through a Classic pool and so this will be routed through pool 1249. \n## About Celestia \nCelestia is a new type of blockchain that aims to launch a new modular paradigm where each chain is minimal in composition and highly specialized to perform specific tasks. This specialization provides breakthroughs in scalability, flexibility, and interoperability, enabling developers to build blockchain applications for mass adoption. \n\nCelestia is specialized as a data availability blockchain with the TIA token used to pay for blobspace. This allows new blockchains to be spun up without their own native token, instead using TIA similarly to ETH on Ethereum-based rollups. Developers may opt to bootstrap their chain quickly by using TIA as a gas token and currency, in addition to paying for data availability. In this mode, developers can focus on creating their application or execution layer instead of issuing a token right away. \n\n Forum Thread: https://forum.osmosis.zone/t/celestia-launch-expedited-proposals/538
