feat(toml): array-index paths in set/delete, incl. array-of-tables (#59)

`Toml::set`/`delete` now handle a path ending in an array index, the follow-up
its own TODO named. A trailing `[n]` sets, replaces, or appends (`n == len`) an
array element, and auto-vivifies the array:

  .bin[1] = {name = "b"}   # append a new [[bin]] block
  .bin[0] = {name = "z"}   # replace element 0 in place, siblings untouched
  .xs[2]  = 3              # append to an inline array
  del(.bin[0])             # remove an array-of-tables element

A table value in an array-of-tables (or an absent/empty array) renders as a
`[[key]]` block; scalars and arrays use an inline array element. Negative
indices count from the end; an out-of-range set errors (naming the append
index), an out-of-range delete is a jq-style no-op. Field-path set/delete is
unchanged (the field walk is extracted to shared helpers).

Lossless: replacing or appending one element leaves every untouched sibling,
comment, and blank line byte-for-byte, verified by a new array-of-tables
round-trip fixture and the array_index_set_and_delete test.

Closes #59. Bumps edikt-toml 0.2.3, edikt 0.2.5.
