Book section: Dynamic data structures (draft)

[japaric]

In this section we cover how to get data structures like std::Vec and std::String working in #[no_std] applications. There are two ways: (a) using the alloc crate, #[global_allocator] and #[alloc_error] -- heap allocated collections -- and (b) using the heapless crate -- fixed capacity collections. There should be a subsection that covers the advantages and disadvantages of using one or the other.
