Add allocation commands

[trufae]

We want to manage the heap from Frida.. sooo:

• das hello world -> Memory.allocString('hello world')
• ds 1024 -> Memory.alloc(1024);
• ...

Frida allocations are kept until a js reference to them exist, so i propose to:

• keep a dictionary / set of all of them
• when an allocation is created, the address of its pointer is returned / displayed to r2 user
• when user is done using it, there should be a command like ds- [addr] with optional address to remove a specific allocation, without args to bulk remove them all

I have been thinking in making dmh work with frida too. Only for linux atm. But being able to catch heap overflows at runtime using frida and analyze the chunk changes with r2 will be another good use case for r2frida
