Add new DEX's

1. (/config/dexs.json) Add the DEX name, together with it's Proxy/Router/Quoter/Factory contract address(es) found in the DEX documentation to the /config/dexs.json file.

2. (/abi/NEWDEXNAME.json) Get the ABI code from the individual DEXs GitHub repo or contract address on etherscan.io. And add it to a /abi/DEXNAME.json file. Depending on the DEX it will be the Router/Factory/Exchange/Quoter json files.

3. (/lib/contracts.ts) Create contract instance(constant) with address and ABI for specific DEX in lib/contracts.ts file. If contract address is depended on token pair like Mooniswap, create function to get contract instance for specific token pair.

4. (/lib/NEWDEXNAME) Add the "getCalldata.ts" file under /lib/DEXNAME folder you create if needed. Add functions(get calldatas for price and swap) in getCalldata.ts file.

5. (/lib/contracts.ts): export a new, shorter name as a constant of the DEX in /lib/contracts, by making the constant a combination of the Router/Quoter/Factory/AbiItem, and anything else that is required.

6. (mainnet/origin/common.ts): add the new short name of the router/quoter/dex info in the "import { " section.

Import the "getPriceOnDEXNAME" in the same file as step 6 (around line 25)

As well as adding a new constant export of the DEXs name array to display on screen(around line 35).

Also make sure to add the new DEX with a 2-3 char name as a constant in the "getAllQuotes" section (around line 60).

Modify and add the relevant information/constants in the "const result: Multicall" section. "getAllQuotes" function returns array of quotes and contract instances(router).

7. (mainnet/origin/trader):

import "getSwapOnDEXNAME" function for the new dex in the "header".

add the dex to the "const runBot" section as an 'else if' statement by adding it below the rest as a new ID (in order).
