Increasing Word Weights

The weight of an English word can be calculated by summing the ASCII code point for each character in the word, excluding any punctuation:

"Wouldn't" = 87 + 111 + 117 + 108 + 100 + 110 + 116 = 749

Write a function that takes a sentence as a string, returning True if all word weights increase for each word in the sentence, and False if any word weight decreases or remains the same. For any single-word sentences, return True.

Examples

increasing_word_weights("Why not try?") ➞ True
# 312 -> 337 -> 351 (weights increase)

increasing_word_weights("All other roads.") ➞ False
# 281 -> 546 -> 537 (537 is less than 546)
