Feature: Ticker lookups

[dhruvan2006]

The Search module seems like it has been heavily nerfed for searching just tickers. It seems more useful now for fetching news.

Changes:

I have therefore added a new class Lookup that provides the functionality as provided on this page
https://finance.yahoo.com/lookup/?s=apple

Example:

To perform the same as the link above:

import yfinance as yf

all = yf.Lookup("apple").all
print(all)

Closes #2359

Can you explain the difference between this and:

yf.Search("apple").all

[dhruvan2006]

As I said Search got nerfed and only returns a maximum of 5 quote results. Lookup uses a different endpoint dedicated to searching tickers.

Ah ok

Suggestion: auto-parse the JSON into a dataframe e.g.:

pd.DataFrame(lookup.all).set_index('symbol')

I don't need that and the current list of dicts return type seems to be in line with what search does:

import yfinance as yf
print(yf.Lookup("apple").get_stock()[0])
print(yf.Search("apple").quotes[0])

yields:

{'exchange': 'NMS', 'industryLink': 'https://finance.yahoo.com/sector/technology', 'industryName': 'Technology', 'quoteType': 'equity', 'rank': 33269, 'regularMarketChange': 4.1699981689453125, 'regularMarketPercentChange': 1.947687029838562, 'regularMarketPrice': 218.27000427246094, 'shortName': 'Apple Inc.', 'symbol': 'AAPL'}
{'exchange': 'NMS', 'shortname': 'Apple Inc.', 'quoteType': 'EQUITY', 'symbol': 'AAPL', 'index': 'quotes', 'score': 33269.0, 'typeDisp': 'Equity', 'longname': 'Apple Inc.', 'exchDisp': 'NASDAQ', 'sector': 'Technology', 'sectorDisp': 'Technology', 'industry': 'Consumer Electronics', 'industryDisp': 'Consumer Electronics', 'dispSecIndFlag': True, 'isYahooFinance': True}

But I think the author of the PR, @dhruvan2006, should mainly chime in here.

Changed to return dataframe. I think having it so aligns well with the rest of the package.
