Baseline V2 DTL Callback

[0xJem]

• Implements a DTL callback that deposits all of the auction proceeds into an existing (but not initialised) Baseline V2 stack. Also includes allowlist variants.
• Adds scripts for working with FPB & Baseline Allocated Allowlist auctions: create, place bid, settle
• Improvements to salt generation scripts to reduce redundant code and values

TODOs:

• [x] Get tick ranges reviewed by Baseline
• [ ] Scripts to set up Baseline stack

Updated with the latest BPOOL interface and made the appropriate changes wrt pool initialisation

I propose closing this PR, as the code has been moved into axis-periphery and axis-utils
