[Proposal] API redesign discussion

API design proposal, as mentioned in PR #15 This would make the API designs more semetically pretty.

dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoUpdate((matched, newItem) => new Item()
    {
        Field = newItem.Field,
		Visit = matched.Visit + 1
    });
dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoUpdateAsync((matched, newItem) => new Item()
    {
        Field = newItem.Field,
		Visit = matched.Visit + 1
    });
dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoUpdate();
dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoUpdateAsync();
dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoNothing();
dbContext.Items.UpsertRange(newItems)
    .OnConflict(x => x.IdentitcalField)
    .DoNothingAsync();

// Infer the match fields to detected primary keys or alternative keys,
// this would make OnConflict funcional call optional
dbContext.Items.UpsertRange(newItems);
dbContext.Items.UpsertRangeAsync(newItems);
