Feature/favorites

[reneepinna]

What I did:

• Create a favorite context with a custom provider and hook
• Allow the favorite context to add and remove favorited breweries
• Allow the favorite context to track if the favorite local breweries filter is on and create a list of breweries to be displayed
• Connect filter functionality to Map and Brewery container
• Add a button to favorite/unfavorite a brewery
• Created a navLink to the favorites page
• Created a favorites page that holds all favorite breweries

Additional Changes:

• Moved the header into the homepage
• Formatted the phone number for brewery cards
