Rework DB returns to be more functional

[larsyngvelundin]

Rather than returning an array like:

[(70, 'eth', 'eth', 'ether', '0x1F98431c8aD98523631AE4a59f267346ea31F984', '0xA30EBe412e17aE91E80F36DED94B0AB09f99ca89', 1698514091, '0x53c6A49e8B07D7b05B81d65CaB43e360B8fbeA43', 'dev', '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2', 'WETH', 'uniswap3', 18450185)]

It would be better to process that list within DB and return a Dict or something similar to this:

{
    id: 70,
    net: 'eth',
    pool_main_contract: '0x1F98431c8aD98523631AE4a59f267346ea31F984',
    pool_address: '0xA30EBe412e17aE91E80F36DED94B0AB09f99ca89',
    time_created: 1698514091,
    token1_address: '0x53c6A49e8B07D7b05B81d65CaB43e360B8fbeA43',
    token1_symbol: 'dev',
    token2_address: '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
    token2_symbol: 'WETH',
    dex: 'uniswap3',
    creation_block: 18450185
}

Then the information can be easily accessed by doing pool.creation_block instead of the harder to read and debug pool[12]
