Update adapter for Teller pools

[rbcp18]

This PR updates totalSupplyUsd to properly show the total liquidity (lending token) that was supplied into the pool. Now, the pool data returns the correct tvlUsd and totalSupplyUsd metrics. This maps to the onchain data.

For example:

{
    "pool": "0xec5446bbf7c40557d4d4041dfcce745a4374d0f1",
    "chain": "Ethereum",
    "project": "teller",
    "symbol": "PIXL",
    "mintedCoin": "USDC",
    "tvlUsd": 76837.48433983672,
    "totalBorrowUsd": 26522.333939427197,
    "totalSupplyUsd": 103359.81827926391,
    "ltv": 0.3333333333333333,
    "apyBaseBorrow": 50.13203958384825,
    "apyBase": 12.863980578167817,
    "underlyingTokens": [
      "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
      "0x427a03fb96d9a94a6727fbcfbba143444090dd64"
    ],
    "url": "https://app.teller.org/ethereum/lend/pool/0xec5446bbf7c40557d4d4041dfcce745a4374d0f1"
}

i think we need to make some other changes to this adapter, lets take this pool as an example: https://app.teller.org/ethereum/lend/pool/b65320e0e814aac23b70545331bf004820ba9553

pls confirm:

• the 17% yield is for supplying USDC (any other conditions to receive this yield?)
• someone who wants to borrow USDC from this pool needs BEAM as collateral
• there is no yield on supplying BEAM as collateral
• if someone borrows USDC from this pool by supplying BEAM as collateral they pay ~50% apy on the borrowed USDC

if correct, we need to make these changes:

• if adapter symbol = the lending token like USDC -> apyBase = the supply apy of the lending token (17%), tvlUsd = total deposits of lending token & we need to omit all other lending fields
• if adapter symbol = the collateral like BEAM -> apyBase = 0 (cause user doesn't earn anything by supplying collateral), apyBaseBorrow = ~50%, mintedCoin = USDC, totalSupplyUsd = tvlUsd = the total $ beam collateral amount, totalBorrowUsd = the USDC borrow amount

Previous comments confirmed 👍

Recent commit addresses the required changes. For the USDC/BEAM pool used as an example:

• tests are failing cause of duplicated pool ids
• for the "lending" side like this:

{
    pool: '0xb65320e0e814aac23b70545331bf004820ba9553',
    chain: 'Ethereum',
    project: 'teller',
    symbol: 'USDC',
    tvlUsd: 180089.4445,
    apyBase: 17.71104340488303,
    underlyingTokens: [
      '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      '0x62d0a8458ed7719fdaf978fe5929c6d342b0bfce'
    ],
    url: 'https://app.teller.org/ethereum/lend/pool/0xb65320e0e814aac23b70545331bf004820ba9553'
  }

we need to add poolMeta: "BEAM" cause there are many USDC pools

[rbcp18]

poolMeta: now added to the "lending" side. For example:

{
    pool: '0x0147dd4bba5e33e7f9231a812e1aff5bb19b9827',
    chain: 'Ethereum',
    project: 'teller',
    symbol: 'USDC',
    poolMeta: 'MASA',
    tvlUsd: 171498.7357,
    apyBase: 45.75621709314477,
    underlyingTokens: [
      '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48',
      '0x944824290cc12f31ae18ef51216a223ba4063092'
    ],
    url: 'https://app.teller.org/ethereum/lend/pool/0x0147dd4bba5e33e7f9231a812e1aff5bb19b9827'
  }

tests are failing cause of duplicated pool ids

this is still missing hence why tests are failing, are you testing locally?

[rbcp18]

Thank you. Duplicate pool Ids issue addressed 👍

Tests seem to be passing now:

 PASS  ./test.js
