Updates, typo-fixes, and player-facing map!

Hey all,

Lim-Dul from the Mausritter discord gave me some very nice feedback after prepping to run this, which lead to some updates:

• More statblock callouts, including total counts for the number of creatures in each room by default
• A player-facing map for use with virtual table tops with the secret wall in the foyer obscured by hatching so it can be hidden with fog of war
• Many typo and language fixes

Hope you enjoy the usability fixes, and please reach out if you notice any issues!

Thanks again to Lim-Dul!
