Option to prevent deletion of orphan comments about toml-sort

[brodybits]

Likely related:

[a-section]
# this comment is preserved
config1 = 123

# this orphaned part all gone
# config2 = 456

My apologies for the incorrect example, just tested this example (now updated to add some wanted & expected spacing):

[a-section]
# this comment is preserved
config1 = 123

# this orphaned part is removed
# config2 = 456

[b-section]
config3 = 789

# seems to be preserved at the end:
# config4 = 901

P.S. adding another case:

[a-config]
list1 = [
  "abc", # first
  # second:
  "def",
  # orphaned part removed:
  # "maybe later",
]
